duplicate error message makes it difficult to determine code location

[davidkel]

There are 2 identical error messages in the code making it difficult to work out which code path occurred.

		if firstEndorser == nil || firstResponse == nil {
			return nil, rpcError(codes.Aborted, "failed to endorse transaction, see attached details for more info", errDetails...)
		}

	if endorsements == nil {
		return nil, rpcError(codes.Aborted, "failed to endorse transaction, see attached details for more info", errorDetails...)
	}

in api.go

Would be good to make these distinguishable or have error log messages in the peer so that you have something in the peer logs to indicate the code path
