Fix resizing outline showing when using the corner to close the window

How to reproduce this bug:
1) Disable Live Resizing
2) Set Triangle Long Press Action to Close App
3) Open any resizable window and long press the triangle.

The resizing outline appears but doesn’t disappear

Add a broadcast to hide the outline when onDestroy is called
