CRM-20023: Do not require state_province value to use state_province_id value.

[xurizaemon]

Both Google and Yahoo geocoders would ignore a passed in 'state_province_id' unless it was accompanied by a non-empty 'state_province' value.

This resolved only to "U.S.A" -

CRM_Utils_Geocoder_Google::format([
  'state_province_id' => '1022',
  'country' => 'U.S.A'
]);

But this trickery would resolve to "Minnesota, U.S.A"

CRM_Utils_Geocoder_Google::format([
  'state_province' => 'Blueberry muffin',
  'state_province_id' => '1022',
  'country' => 'U.S.A'
]);

With the submitted patch, the former will correctly resolve the state_province_id.
