Tweak EXIF extraction code to be more robust.

* Create Exif_Record_Model to track whether we've scanned the EXIF
  data for this photo or not.  This allows us to track photos that
  don't have EXIF data (and won't have any Exif_Keys)

* Blow away old Exif_Keys when extracting, else we hit unique
  index constraints.

* exif::_get_stats() -- before it was running the task forever
