Change Details

This is a temporary change on the `keyserver` side that keeps things working as they are when client hits `create_multimedia_message` with the new payload. We're basically translating `mediaMessageContents` back to `mediaIDs` by pulling out the `uploadID` property. This ensures that the client continues working as normal with the new payload while we're still working on implementing the "new" `multimediaMessageCreationResponder`.
