Bug: Passing group -1 throws API usage exception.

[cblackburn]

The following Python tests:

integration.permissions.testSaveWithNegBadLink
integration.permissions.testSaveWithNegOneExplicit

the tests fail for the following reason:

ApiUsageException: No valid permissions available! DUMMY permissions are not intended for copying. Make sure that you have not passed omero.group=-1 for a save without context

when they are expected not to. See full exception for one failure in comment below.

Since the actions are actually failing, pushing this along with #11375 out of 4.4.9. For reference, likely the only thing that has happened is that changes in the code path put a more stringent check before the previous check so that a new (perhaps less-specific) exception is being thrown. Though that's an API break, it's unclear when these happened, and by now, we may be relying on that new logic. This will require a brief discussion when the time comes.
