With an existing instance running, run gnome-boxes again.

Don't crash when running Boxes while it's already running

When running Boxes while an instance is already running, the
new instance crashes in App::suspend_machines. This happens because
App::collection is null and App::suspend_machines tries to dereference
it. This commit just silently exits from App::suspend_machines in such
situations as there will be no machines to save anyway.
