Admin users cannot specify municipality of municipal user when changing role

[sannphilbrick]

Describe the feature. What should a user be able to do?
We would like admin users to be able to change the role of municipal users who were in the system from the old site to municipal users. The biggest thing preventing us from doing that now is that we can't then specify which municipality they're a part of

Why do we need this feature?
It makes it difficult to change the role of older users so that they can enter projects without moderation

Once the user has been changed to 'municipal', we should put a dropdown box in the "Municipality" column where the admin can assign/change any municipal user's designated municipality.
