Subject: [PATCH] Ensure that lcnt server is terminated after lcnt:stop/0

This makes the nightly tests slightly more stable as they assert
that the server isn't alive when lcnt:start/0 is called, which it
could still be since the stop command was a plain gen_server call
that didn't wait until the termination was completed.
