ST_AREA does not work on GEOMETRYCOLLECTIONs in maria-5.3-gis

[Philip Stoev]

ST_AREA returns NULL when passed a GEOMETRYCOLLECTION .

select ST_AREA(ST_GEOMCOLLFROMTEXT(' POLYGON((0 0,4 7,1 1,0 0))'));
returns 1.5

select ST_AREA(ST_GEOMCOLLFROMTEXT(' GEOMETRYCOLLECTION(POLYGON((0 0,4 7,1 1,0 0)))'));
returns NULL

postgis returns 1.5 in both cases.
