* Remove access token refreshing logic. The new calling pattern for an extension is that they should just always call `getSession` before doing something with it. The session that returns will be valid because MSAL will refresh any access tokens that are close to expiry using the refresh tokens that it has
* NOTE: access tokens expire after 1hr. Refresh tokens expire after like... many days.
* Have `createSession` fire an `onDidChangeSession` event so that the badge goes away
* Improved logging messages
* Moves the `setupRefresh` stuff into the CachedPublicClientApp simplifying things a bit
* Uses a ScopeData class to handle all scope operations fixing an issue where we were passing in the wrong array into the `acquireTokenInteractive`
