PKGPATH needs to be available in Fuel v1.3+

In Fuel v1.3+, the 'package_paths' config variable is already defined, which means
core/migrate.php _find_packages function uses /Config::get to get that value and does not "default" to PKGPATH that is set in OIL.

This effectively means you have to add PKGPATH back into 'package_paths' to get ninjaauth migrations to work.
