 {{{
 #!CommitTicketReference repository="" revision="16659"
 put back old sfcgal test (except use \i, and have the query be what was in
 sfcgal one), the sfcgal one was different
 Closes #4131
 Revise ST_ConcaveHull to use ST_UnaryUnion(ST_Collect..) (cause I know
 sfcgal doesn't replace with it's own implementation / a bit of a cheat)
 Take out some ST_Union calls I think are over compensating.
 References #3638
