Ensure settings provider joins the rescue party

The settings provider has logic to incrementally reset state
in an effort to recover from pushing a bad value putting the
system in a bad state. The settings provider was not force
persisting its state after a reset so after the reboot we
lost the reset changes. Also while resetting we were also
resetting the package name leading to a promotion of the reset
value to being set by the system. Updated the tests and while at
this added logic to synchronously persist critical settings
such as device provisioned.

Test: All tests pass. Manually tested end-to-end rescue party
