ico-input.mgr: avoid crashes in case the assigned app were not running

	If system-controller directs some input to an application that
	does not run and the input state changed, weston crashes in
        ico_device_input_event() routine. This patch fixes this problem
        by avoiding to deliver input state changes to applications that
	did not run or have not registered yet a proxy.
