SQL error in Views using geo_data fields

The geo_data views handler adds an extra alias to the last field of the internal fields (srid, wkb, bbox, centroid) returned by geo('field_select', ... ) when it uses $this->query->add_field().

See line 9 of the following SQL written by Views/views_handler_field_geo_data:

 1 SELECT node.nid AS nid,
 2    node.title AS node_title,
 3    node.uid AS node_uid,
 4    node.type AS node_type,
 5    node_revisions.format AS node_revisions_format,
 6     SRID(geo) as geo_srid, 
 7     AsBinary(geo) AS geo_wkb,
 8     AsBinary(Envelope(geo)) AS geo_bbox,
 9     AsBinary(Centroid(geo)) AS geo_centroid AS node_data_field_area_field_area_value,
10    node_data_field_area_geo.label AS node_data_field_area_geo_label,
11    node_data_field_area_geo.id AS node_data_field_area_geo_id
12  FROM node node 
13  LEFT JOIN node_revisions node_revisions ON node.vid = node_revisions.vid
14  LEFT JOIN content_field_area node_data_field_area ON node.vid = node_data_field_area.vid
15  LEFT JOIN geo_data_ssw_regions node_data_field_area_geo ON node_data_field_area.field_area_value = node_data_field_area_geo.id
16  WHERE node.type in ('organization')
17  GROUP BY nid, node_title, node_uid, node_type, node_revisions_format, node_data_field_area_geo_label, node_data_field_area_geo_id

The attached patch removes the alias from the add_field() method call, and fixes a typo in geo_field_select().
