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 : https://github.com/inrupt/solid-ui-react/blob/52cbbc4169abf494a0d00a2c8d6b16a8e6668386/src/hooks/useSession/index.tsx#L37-L47
• 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) https://github.com/inrupt/solid-ui-react/blob/52cbbc4169abf494a0d00a2c8d6b16a8e6668386/src/context/sessionContext/index.tsx#L190-L200

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
