[BUG] Actions for projects visible to users

[davidjumani]

Describe the bug
Buttons to edit / suspend / delete / add users allowed to a regular user of a project. Should be hidden unless the uesr is a project admin

[yadvr]

Critical added, while no functionality is broken users shouldn't see button they're not authorised to press/see.
