WIP: incoming non-signal call while in outgoing signal call

Marking Signal-Call as started, changes the incoming call screen for
subsequent calls to show "Accept & End", "Send to VoiceMail" and "Accept
& Hold" instead of just "Accept" & "Decline"

Though - we don't support Holding. What we really want to see is just
"Accept & End" and "Decline | Send to Voicemail"
