Fix workgroup access
Closes #287
What does this MR do?
Fixes a mistake when refactoring the WorkGroup page that lead to effectively no permission checks for workgroup edit.
Maybe deploy as hotfix to production as well?
I also added a test...
How confident are you it won't break things if deployed?
test looks good.
