ComboBox: change currentIndex (if applicable) when focus is lost

When the user enters text into an editable ComboBox that matches
the text of an entry in the model, and then tabs out to another
item, the currentIndex should be changed to that entry.

This brings the behavior of ComboBox in line with QComboBox.
