Before this commit, when a local device has not found been found in a object-replication run, the policy was not mentioned in the error log. But it is of interest to know the policy, for example for error searching, when no local device has been found. Change-Id: Icb9f9f1d4aec5c4a70dd8abdf5483d4816720418
