With MP_Forms, no files are sent as attachments with NC

[zonky2]

If the NC has a token such as ##form_upload## in the "Dateianhänge via Tokens" field, no files are attached. It is the standard upload field (single upload).

If you send the form without MP_Forms, it works.

MP_F Version 5.2.0 and 5.2.1 + NC 1.7.10 + Contao 4.13.52

with MP_F 5.1.2 the attachment works fine
