Run app without service when no Flics attached
I use the Flic app solely to connect to the Hub - I have no buttons connected to my phone and am unlikely to do so in the near future. Whenever I run the app the Flic service starts in the background, and doesnt stop when I exit the app (to be clear, this is via the explicit Exit App option in the menu). I don't need or want the background service running when there is no reason for it to be running.
