Need the spatial coords to carry correct spatial_ref and crs

[emmaai]

Expected behaviour

The spatial coordinates x and y should have correct spatial_ref and crs after reproject

Actual behaviour

Only the values are changed but with the old spatial_ref and no crs. Hence the results.geobox crs is wrong.

datacube-core/datacube/virtual/impl.py

Lines 909 to 910 in 6ee0462

	for name, coord in dst_geobox.coordinates.items():
	result.coords[name] = (name, coord.values, {'units': coord.units, 'resolution': coord.resolution})

Steps to reproduce the behaviour

@emmaai I somehow did not manage to reproduce the issue. See PR #1074 please.
