Scheduled Diagnostics Failing every 3rd time or so with new Auth

[metheos]

The default scheduled diagnostics refresh falls on the 60 minute expiration of the Microsoft token.
I've updated my OnstarJS fork to do a refresh of either token if they expire in less than 5 minutes when they are requested.
This mirrors the 5 minute re-auth of the old OnstarJS mechanisms.

@metheos, please LMK if everything works as expected now. Thanks!
