From: Antonio Quartulli a@unstable.cc
Since the conversion from kthread to queue worker it is not possible to run more than one "sender" session at a time. For this reason, checking if another session to the same destination is already scheduled is not useful anymore.
Remove such check and allow the user to enqueue a new session to a previously targeted node.
