Make sure a pending call timeout isn't assumed.

* dbus/dbus-connection.c (_dbus_connection_attach_pending_call_unlocked):
  Don't assume that the pending call has a timeout.
  (connection_timeout_and_complete_all_pending_call_unlocked): check that
  the timeout was actually added before removing it; this safeguards us
  if the pending call doesn't have a timeout.
