Fixes#6220
Fixes the issue with the mutual contact icon showing when just added.
It also does a huge cleanup of the codebase to remove isContact and replace it with either isAdded, when we care only about if we added, or isMutualContact if we want the contact to be mutual
Also fixes an issue with the MessageContextMenu not reflecting the added state correctly.

imports.
