fix(clerk auth): set auth state to loading while reauthenticating

[jtoar]

Context: https://community.redwoodjs.com/t/clerk-the-signup-and-signin-components-cannot-render-when-a-user-is-already-signed-in-unless-the-application-allows-multiple-sessions-since-a-user-is-signed-in-and-this-application-only-allows-a-single-session/4694/5.

This is to solve another mismatch in auth state between Redwood's auth provider and Clerk. We know if the user is logged in and auth has loaded before we know the exact details of the current user, so we can update the state to reflect this earlier and avoid the router hanging on to old state.
