7579	Saving into SRID=-1 field causes st_transform error	Robert Coup	jbronn	"Currently if you define a `GeometryField(srid=-1)` then save a value with a `srid != -1`, then Django will attempt to transform the geometry ''to'' -1, causing a DB error.

I've attached a simple patch for Postgis but I suspect the same issue will occur in the other backends - is `geoapp` the best place to add tests for this?"		closed	GIS	gis		fixed	srid		Unreviewed	1	0	1	0	0	0
