The GCStoGCS operator using the _replace=False_ flag and specifying _source_object != destination_object_, will not work properly, because it is comparing [apples](https://github.com/apache/airflow/blob/main/airflow/providers/google/cloud/transfers/gcs_to_gcs.py#L351) with [pears](https://github.com/apache/airflow/blob/0dd70de9492444d52e0afaadd7a510fc8a95369c/airflow/providers/google/cloud/transfers/gcs_to_gcs.py#L357).

Cause: the _prefix_ in the _pears_ case needs to be calculated from the _destination_object_, however, it is coming from the _source_object_.
