Bug 1094781 - [Dialer][Callscreen] The call on hold shouldn't be red (follow up 977588)

You can safely delete this line too. Take into consideration that body.single-line implies that #call.big-duration. In fact, I just notice these 2 classes may be duplicating code. There's is a case when body.single-line should not imply #call.big-duration but I just verified that we keep the #calls.big-duration even in that case :O
