changed the description

I added a test (locally) that expose issues reported on qgis-otb-plugin#30 (closed) and https://issues.qgis.org/issues/21373 https://issues.qgis.org/issues/21374

I have a fix (on test) for plugin code that will allow us to work with QGIS 3.2+ and otb 6.6+

I will update in detail about that in qgis-otb-plugin#30 (closed)

@aregimbeau , Thanks for artifact. I kind of like that word in development (Warehouse13

artifacts aren't working. qgis show this error:
