Resolves: tdf#102293 triple click results in visually unselected word

in previously unselected textboxes in impress

started happening after...

commit 16c7f8916661df24f4681ec82f6bd4d7ad85d141
Date:   Tue Jan 12 16:36:49 2016 +0000

    tdf#97075 - don't render sdr overlays before we paint

in impress instead flush the overlay after activating the edit object
if we go on to put the cursor in there. Seems to work.
