When investigating issue #13548, I found that gosub

handling in app_queue was just completely wrong, mostly
because the channel operations being performed were being
done on the incorrect channel.

With this set of changes, a gosub will correctly run on
the answering queue member's channel. There are still crash
issues which occur if there are dialplan syntax errors, so
I cannot yet close the referenced issue.
