Use fixture rather than multiple parametrize for naming arguments

This commit reduces the overall number of tests by testing --plate_name and --plate_description arguments for plate imports only.
Re-add support for --debug=ALL
Pass non-null transfer for proper annotations

Petr pointed out that the merge build was missing
symlink decorations in the clients. On further
inspection, no annotations were being created since
a null was being wrongly passed to `fillData`.
Fix failing test_import.py naming integration tests

For some reason, depending on the method used to run the tests, the Object:id
line is not always at the same position in the stderr. This commit applies the
same strategy as the one used in test.integration.library.import_image() i.e.
loop over the stderr lines (in reverse order) and break when a match is found.
