loaded profile cannot be obtained from session hook, and skipping the loading breaks the SessionContext logout updates

Bug description

There is a problem with the way the profiles are used in the session init.
The problem is two-fold :

• profiles are loaded by default on session init, and set in a state that is part of the SessionContext. However these profiles are not exposed by the useSession hook, making them useless, and therefore wasting an HTTP request on login :
  

  solid-ui-react/src/hooks/useSession/index.tsx

  Lines 37 to 47 in 52cbbc4

  	export default function useSession(): SessionInfo {
  	const { session, sessionRequestInProgress, fetch, login, logout } =
  	useContext(SessionContext);
  	return {
  	session,
  	sessionRequestInProgress,
  	fetch,
  	login,
  	logout,
  	};

• the skipLoadingProfiles flag can be used to remove that behaviour. However, it turns out the profile state is the only variable that triggers a session context update when logging out (the session object does not get updated by a logout, only its internal isLoggedIn field)
  

  solid-ui-react/src/context/sessionContext/index.tsx

  Lines 190 to 200 in 52cbbc4

  	return (
  	<SessionContext.Provider
  	value={{
  	session,
  	login: contextLogin,
  	logout: contextLogout,
  	sessionRequestInProgress,
  	setSessionRequestInProgress,
  	fetch,
  	profile,
  	}}

So trying to disable the profile loading actually disables the logout updates one can expect from a SessionProvider, thereby mandating the explicit use of an onLogout callback.

Expected result

• have the profile exposed through the useSession hook
• be able to use skipLoadingProfiles while relying SessionProvider to trigger proper updates on logout
