Issue with SetParameterString for ListView parameters

Description

in otb::Application, for ListView parameters, the SetParameterStringList selects from a vector of string the corresponding element in the ListView whose name can be found in the vector. However SetParameterString does not have the same behavior, it selects the element in the listView whose key correspond to the input string. This leads to some weird behavior, as the key names are usually managed by the application and are usually unknown to the users.

Example

Using PolygonClassStatistics:

import otbApplication as otb                                                                                                                                                                       

appStat = otb.Registry.CreateApplication("PolygonClassStatistics")                                                                                                                                 

img = "img.tif"
db = "vec.sqlite"   # vec.sqlite contains a field named my_id                                                                                                                                                                               

appStat.SetParameterValue("in",img)                                                                                                                                                 
appStat.SetParameterString("out", "stats.xml")     

                                                                                                                                                       
appStat.SetParameterValue("vec",db)   # Here UpdateParameters is called by the wrapper and the list view is initialized. for the my_id field, an element is added to the listView, with the key myid (PolygonClassStatistics only keeps the alphanumeric characters) and with name my_id                                                                                                                                                               

appStat.SetParameterString("field", "my_id")   # error, my_id cannot be found in the list view keys                                                                                                                                                
appStat.SetParameterString("field", "myid")   # OK, myid can be found in the list view keys                                                                                                                                                           
appStat.SetParameterStringList("field", ["my_id"])   # OK, my_id can be found in the list view names                                                                                                                                                

appStat.ExecuteAndWriteOutput()

Using RadiometricIndices:

import otbApplication as otb                                                                                                                                                                       
 
app = otb.Registry.CreateApplication("RadiometricIndices")
app.SetParameterStringList("list", ["Vegetation:NDVI"])  # OK, Vegetation:NDVI can be found in the list view names
app.SetParameterString("list", "Vegetation:NDVI")  # Error, Vegetation:NDVI can be found in the list view keys
app.SetParameterString("list", "ndvi")  # OK, ndvi can be found in the list view keys (but this is not documented)

Note

this really depends on how the application manage the list view, but I think SetParameterStringList and SetParameterString should have the same behavior, and for most (all ?) applications the behavior of SetParameterStringList is the expected one.
