Subject: [PATCH] Update coord attrs in _update_metadata_increased_resolution()

The coordinates of a DataArray that has been interpolated will have
attrs that are not consistent with the new DataArray. This commit
updates _update_metadata_increased_resolution() to also replace the
attrs of the DataArray's coords with the attrs of the new DataArray.
