BUG: error after edit group owner

[pwalczysko]

Noticed after testing of ​https://github.com/openmicroscopy/openmicroscopy/pull/2100.
See mainly the post-merge discussion there.

!There is a bug which is still present in this workflow (see screenshot above).

• login as user-4
• do not go to Project tab, instead expand immediately the Admin tab
• do not Refresh
• go to the group selection menu (still in Admin tab)
• you can put read-only-1 to display (in Admin tab) -> not expected (user-4 is not an owner of that group)
• you can expand the read-only-1 group and pick user-4 (=yourself)
• you can edit the user-4 and change his default group
• press Save -> error occurs
• in order to repeat this bug, it is necessary to have a group setup as indicated in the screenslhot (user-4 is also a member of a Test group and one more group, (as well as the read-only and read-write group) = member of 4 groups, and an owner of 2 of them (the Test one and the read-write one). Also, prior to navigating to Admin tab, edit the group selection in Project tab and untick the "read-only group". Also, when putting the read-only group to display in Admin tab, do use "Show all" tick.
