Facilitate Hanging Up Pending Emergency Call

Corrects the hangup logic for calls that have not successfully returned
a telephony Connection. Before, we only used to hang up calls that were
backed by a telephony Connection. This made calls hang that were waiting
for the telephony Connection to be established (such as Emergency
Calls or calls with bad service).
