fix(switcher): drop a parked create when its machine's connect is called off

Disconnect clears the in-flight connect, so finish_connect never runs and
the PendingCreate outlived the intent behind it: the next successful
connect to that machine would have silently created a workspace nobody
was waiting for anymore.
