Add some necessary hangup commands in the case that forwarding
a call fails

1) Hang up the original destination if the local channel cannot
   be requested.
2) Hang up the local channel (in addition to the original destination)
   if ast_call fails when calling the newly created local channel.

This prevents channels from sticking around forever in the
case of a botched call forward (e.g. to an extension which does not
exist).
