Fix requests for senders to submit auto-rageshakes (#12304)

If auto-rageshake-on-UISI is enabled, then when we get a UISI we send the sender a to-device message asking them to also rageshake. Unfortunately, the logic to do so has been broken since c30b263.

Also a few other minor cleanups while we're here.
