Reactivate and fix the “Recalculate Trader Rating” option

[Galixte]

Hi @rfdy,

i found an old option which was inactivated, why ?

Otherwise there is an error for the old users which use your extension because your migration file does not take in consideration your different updates of the code:

General Error
Cannot find module ./../includes/acp/\rfd\trader\acp\main_module.php
