Broken compatibility with php ^7.2

[Dima Edikhanov]

Hey!

One of the latest commits broke compatibility with php ^7.2 by adding a trailing comma after the parameter.

public function emailStatement(
        $id,
        $from = null,
        $to = null,
        $data = [],
        $filterBy = 'Status.All',
        $sendUnpaidInvoiceList = false,
 ) 

I hope that will help find other similar issues so they can be fixed soon.
Thanks for your work!
