Fix Spinner not restoring selection when set to GONE

This CL restores the selected position when AdapterView
gets restored, rather than wait until the next measure/layout
pass to do it. After the change, even when the AdapterView
is set to GONE (i.e. no measure/layout pass), the selection
will still be kept up to date.
