Raised in aCloud Spanner issue, the returnedGoogleAPICallError has acode andgrpc_status_code ofNone.

The issue seems to be at:
https://github.com/googleapis/python-api-core/blob/master/google/api_core/operation.py#L135

TheGoogleAPICallError constructor does not set the code from theerrors argument so the error code contained within it is being lost.
