Properly dismiss the grid combobox editor when it loses focus 

The old way of checking for focus loss caused GTK to be unable to
even open the combobox. This way checks for the event sent when the
list closes and uses that to close the grid editor.

Fixes https://gitlab.com/kicad/code/kicad/issues/4617
