Exporting a layer with two geometry columns to shp, exports first column

[javitonino]

When a layer has multiple geometry columns, the shapefile exporter takes the first one. My expectations here is that it would take the_geom if it is available.

This comes from CartoDB/cartodb#11115, where the drive-time analysis has two geometry columns (center and the_geom), and the exported one is the center.

Test CSV file, center is a point, the_geom is a polygon. The exported .shp file is of type point.
