Correct pydiaotb tests

Description

Correct test exception and data used in test. The code expect an exception to be released but theses exceptions are not handled in test. The test to change is test_configfile.TestConfigFile.test_config_exception for diapOTB and SAR_MultiSlc chains for normal and IW data (total of 4 tests fails)

Also the geom file used in one test is not up-to-date. Thus the test test_resampling.TestResampler.test_run_resampling does not pass.

Definition of Ready

Generic:

• Issue complexity evaluated
• Priority of issue evaluated
• If there is specific test data needed, it should be detailed and available
• If there is a specific documentation/specification need, it should be available to the development team
• Time during the sprint to realize this issue
• Blocking elements resolved (check if non-applicable, detail otherwise the resolved elements)

Definition of Done

Generic:

• No test regression on CI
• Code reviewed by peers
• Code cleaned, no "debug" traces or "TODO" comments kept.
• New code documented

Specific:

• exception now handled in test
• geom file updated -> see explaination in comment
