fix to load conversation list (restricted user status)

when the user status app on server is restricted to only some groups, the capabilities for users that are excluded still contains the "user_status" capability.
For the android talk app, this caused that the conversations were not shown.
With this fix, the conversations will be loaded also if the "user_status" is mistakenly set. Additionally, the option to set the status will be hidden.
