Migrate WebRTC from plan b to unified plan

Browse source 
The in 'MagicPeerConnectionWrapper#removePeerConnection' used method
'PeerConnection#removeStream' was not longer available in the unified
plan. So to make sure that the local stream is disposed, it will now be
done in 'CallActivity#hangup'.

Resolves: #1773
