fix 2 bugs

bugs:
1. I logged in as a new radar admin and changed my password, the success
page was incorrectly styled.  The HTML markup was wrong.  It should be
the same as the other success pages.
2. New Radar unitadmin can log in to PV and see Patients in Unit only.
I should not see Renal Units, Add a unit user, Users in Unit etc etc.
Merge remote-tracking branch 'robworth/develop' into feature/123-PV/Radar-updated-requirements-Radar-group-admin
this 2 files may be conflict

Still don't know why conflict after merging. so take a try.
