res_pjsip_pubsub: Fix assertion when UAS dialog creation fails.

Browse Source 
When compiled with assertions enabled one will occur when destroying
the subscription tree when UAS dialog creation fails. This is because
the code assumes that a dialog will always exist on a subscription
tree when in reality during this specific scenario it won't.

This change makes it so a dialog is not removed from the subscription
tree if it is not present.
