Connection::isLoggedIn() and more robust logout()

isLoggedIn() is just a wrapper around Connection::accessToken() that
returns whether it's not empty. Now, Connection::accessToken() and
Connection::logout() are changed in such a way that if there's
a logout job ongoing Connection::accessToken() will return an empty
value even though the access token is still stored in ConnectionData.
This gives a hint to the rest of Connection and to the client code
that the user is not quite authenticated anymore. Finally, syncLoop()
and sync() have been altered to check isLoggedIn() before proceeding
with their network request.
