getThumbnails_test

[will-moore]

What this PR does

Adds a test based on testing of #5207

As seen in webclient and reproduced in Python, after 'Save to All' getting thumbnail set WITH
omero.group: -1 fails until we get a thumbnail set WITHOUT omero.group: -1

Test reproduces this but uses with pytest.raises(omero.SecurityViolation): to wrap the failing line.
Should be removed when the bug is fixed.

Testing this PR

1. Test should be green.

Want to try adding an integration test to reproduce issue at #5207 (comment) ?

[will-moore]

@mtbc As far as I can see, getThumbnailSet() was failing after 'save to all' but the test I wrote for that is now passing. I'm not sure how to reproduce the latest failures, except maybe to simply add a large number of images to that same test? But if it's failing because "you can't getThumbnailSet() while thumbnails are being re-created", then we don't have a fix for that, right? So this would likely stay as a failing test which might not be very useful?
Also I could try add a failing test for shares if that would help fix the issue?

[mtbc]

Yeah, doesn't sound like it's worth it at this time, does it? Thank you for your thoughts! If there aren't any regressions with shares then I think we're probably good unless IDR depends on them. At least, I'm unlikely in the near future to get to investigating handling in-progress thumbnails!
