Fix regression for answering a ringing call when there are 2 calls already.

In the case where there is already a held and active call and a new
incoming call is being answered, previous logic was to disconnect the
held call and then hold the previous foreground call before answering
the incoming call.

This CL fixes a regression in that functionality.
