[Gravity Forms] Multi-file uploads doesn't work

Reported by @selul. Single file upload works fine. But uploads don't work if multi-file uploads is enabled.

here I think the issue is due to the js files that Ymir's WordPress plugin, i.e the plupload ones which I guess are modified to work with the platform.

I wasnt able to trace down which one but seems like the replacement files somehow changes the endpoint where the file is sent for upload.
