Contacts and adding uers to appspaces is disfunctional

[teleclimber]

Adding an appspace user, you have a dropdown with 3 choices:

• from contact
• use dropid
• email

I know email does nothing for now. Maybe just remove that option.

using contact should maybe work but does not seem to. Fix or remove.

(In the contacts also indicate that they are useless if that's the case).

Looked at the code and DB schema around contacts and there is nothing usable right now. ELiminate email and contact from options. This leaves dropid only. so it goes for now.
