Side effects of project groups page auto-refresh

The 'Project Groups' page automatically refreshes itself every so
often.  Unfortunately, this now causes errors when existing actions
forward to that page rather than redirect to it.

One such problem (after performing a release) was reported and fixed
in CONTINUUM-1560 [1].  But it also happens when adding a project
group.

There are probably more places this needs to be fixed.  Is there an
easy way to identify the actions that are affected by this?
