server: reorder short-circuit in peer termination watcher

This commit reorders logic in the peer termination
watcher such that we short circuit earlier if we
already have pending persistent connection requests.
Before, the debug statement may have indicated that
a reconnection was being attempted, even though it
may have exited before submitting the request to
the connection manager.
