Merge "squat" information
Due to some legacy issues, groups can have a "type" set as "squat, evicted, legalize". This is however a trait of a location, not actually of a group. However, this value is indexed for groups. Location have two different fields (status, squat). Neither seem to be indexed.
We should merge these 3 fields into one for the location entity, and index that for groups.
Closed as duplication of #236
