[GtkComboBoxText] Add checks for id-column/entry-text-column >= 0

If the GtkComboBoxText doesn't have id-column or entry-text-column
set for some reason (value -1), better warn and return. Else, unrelated
assertions fail, and warnings from gtk_tree_model_get_column_type()
are printed, which are not really obvious.
