fix deselect of textbox on slides with images in underlying master

The original work of tdf#55430 tries to select an object under
another one on the second click, but these images are unselectable
so this fails. Red Hat has a whole new shiny bunch of templates which
have such images in their masters.

Check if the object is selectable before continuing
