fix(calls): DM-aware rejoin toast, and no rejoining a DM call that ended (#302)

After a reload during a DM call the toast said "You were in the call in
Bob Builder"; it now says "You were in a call with Bob Builder". DM
calls are never auto-rejoined (it could ring the other person), and if
they have left by the time you tap, the toast says "Call ended" instead
of starting a new, ringing call.

Fixes #302
