Store the selected directory in wxGTK wxDirDialog.

This should help with the selected directory not being remembered since
GTK+ 2.24.11 as apparently gtk_file_chooser_get_filename() doesn't work any
more now after hiding the dialog -- so call it before doing this and save the
result.

Also get rid of the ugly and apparently completely unnecessary OnFakeOk().

Closes #14525.
