Prevent infinite loop when calling get_user_locale() in a 'locale' filter

Using get_user_locale() in a locale filter (for get_locale()) might sound like a good idea, for example to change the site locale depending on our user.

        if ( $condition) {
                add_filter( 'locale', 'get_user_locale' );

However, if one does that and a non-logged in user (or a user without a locale value) visits the site, a infinite loop will be triggered, since get_user_locale() will itself call get_locale() when no user->locale value exists.

Since this only affects logged out users, it feels like an easy trap to miss, and we should prevent that.
