OIDC: persist refresh token (#11249)

Browse source 
* test persistCredentials without a pickle key

* test setLoggedIn with pickle key

* lint

* type error

* extract token persisting code into function, persist refresh token

* store has_refresh_token too

* pass refreshToken from oidcAuthGrant into credentials

* rest restore session with pickle key

* comments

* prettier

* Update src/Lifecycle.ts
