Subject: [PATCH] Try to invoke Myles while the layout plugin is launching

Summary:
The first launch of Myles might produce a lag connected with the fact that Myles daemon needs to start (mainly, set up a Watchman subscription and depending on what state Watchman is in, it could take ~10 secs to initialise).
Therefore, trying to invoke Myles as soon as the Layout Plugin is enabled.
