Destroy the search popup rather than hide

Submitted by Egmont Koblinger Link to original bug (#791712)
Description
Continuing from bug 771165:
Closing the Find dialog should call gtk_widget_destroy() rather than gtk_widget_hide().
This would avoid a badly looking transitioning in Unity7, perhaps other WMs too.
Would need to manually save and restore the contents of the input field/checkboxes though.
