Fix clicking on the scrim when an RS is active.

The CS Panel was destroying the RS controls when it was told to close.
This means that destruction was happening at the time the close was
started rather than when the close was complete. The fix is to
simply remove these premature destroy calls. These destroy calls
are already being made at the correct time in the CS Panel method
destroyComponents which is called by the OverlayPanel when the
close completes.
