use `uri_string()` to get the string from current url

I use `current_url()` and at line 51 I add an extra script in case if user use index.php :)

NOTE : Since url_is() is available start from CodeIgniter 4.0.5, user must update their application.

I remove the helper('auth) since it's no use in there (performance reason) and put the session check at the begin of code, because we need a session data right?

I add defaultLandingRoute to store the default route name after user success to login (depend on the real case) or fail in Permission & Role Filters too

sorry my mistake

The Routes.php now will use reserved routing from Auth.php
