Make RendererExited reset the InputRouter after destroying the window.

Make RendererExited reset the InputRouter after destroying the window.

Destroying an Aura window generates a synthetic mouse move event if the mouse
is inside the window.  This causes the InputRouter to get stuck in a state
where it is waiting for the renderer to ack the mouse move.
