Automatically submit logs from the host client when rageshaking from Element Call

When the user submits a rageshake from inside Element Call, it should let the host client know (via widget action, probably?) to submit its own logs as well.

Originally, a point of caution was: The host client should *only* do this if its rageshake endpoint matches Element Call's rageshake endpoint—I believe we tried to implement this previously and the web team raised this as a concern, that the user might end up auto-submitting logs to a different entity than they intended.

However, now that we have embedded Element Call into our messenger applications, I think this is no longer a concern. Both the application and Element Call will report to the same entity, as configured via the URL parameters. We can just get this done.
