When using a LDAP backend, it's possible that a user won't have the "email" attribute defined, however it should still be possible to edit the other fields.
Steps to reproduce (in an environment with keystone using a LDAP backend):
1. Log in as admin
2. Go to the Users dashboard
3. Select a user that doesn't have an email defined
Expected result:
4. "Edit user" modal opens
Actual result:
4. Error 500
Traceback:
