Fix arguments being initialized twice for tenants:seed command

[morloderex]

Laravel >= 8.32 introduced a new argument to the seed command see laravel/framework#36513.

This is causing our extended tenants:seed command to initialize the options and arguments twice which throws an exception because at the point we call the specifyParameters method in the constructor it has already instanciated the arguments once so the new class argument is already present.

This pr fixes that by removing our call to the specifyParameters method on the constructor sense it's already being called in the parent constructor anyway and the only thing we are really doing is specifying one additional option to the command anyway.
