Fix a bug in 1.4 branch with iax2 channels not being removed when a call was rejected (from the calling box, not the box that denied the

registration). Related to revisions 132466 in trunk, and 132467 in 1.6.0. Earlier I had accidently tested 1.4 with a backport from those revisions, 
so I didn't see this problem (oops).
