Cleaning testThumbs
Test ImageWrapper.getThumbnail (See #10618)

This gatewaytest goes through various combinations
of the uses of getThumbnail(). They are all currently
passing which points to 10618 actually being an API
usage issue.
Final cleanup of test_thumbnailPerm.py

All methods (barring the one expected fail) are now
passing. As with the gatewaytest, the assumption is
that for the thumbnail service to work correctly, a
proper group context must be passed.
Add tests to also check non-omero.group (See #11427)
Pass omero.db.poolsize into security tests
Delay creation of OMERO.security.test context

These tests are marked as `enabled=false` and so won't
be run. They are being instantiated in order to check
for later processing, so the creation of the `OmeroContext`
can be postponed to save time.
Fix some of the other blitz integration test issues

These allows tests to begin running but does not yet
have them green. A significant amount of work is still
needed to have them all passing or to remove those tests
which have become outdated.
