BEGIN_PUBLIC

[iOS] Fixes the file_path is empty when "CreateIncomingInternalPayload" in internal_payload_factory. If empty then use the payload_id for the file_name.
END_PUBLIC

- This is for the way iOS -> Android file transfer.
- CC_MD5 is deprecated in iOS13, change to CC_SHA256
- UIImageWriteToSavedPhotosAlbum, the UIImage* is nil after completion callback to the selector "didFinishSavingWithError". Changes to show image by "showReceivedImage" after write to Photo album.
- "NSDownloadsDirectory" seems have
<<Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “Downloads” in the folder>>. Changes to use "NSTempDirectory".
