Currently the test-watch.service gets started in a loop as long as /testpath exists, so `rm /testpath /testpath-modified` runs into a race condition where if the service was just getting activated, it will create /testpath-modified and make the test fail. This is fixed by making the service RemainAfterExit so that it only starts once, and stopping it manually after we remove /testpath.
