[11.0] Clicking item on Supplier Payment Paid or Debit tab causes field does not exist error

[kwoychesko]

Open an existing Supplier Payment - Paid tab. Click on one of the line-items. You will get the following error:
ValueError: Field payment_group_matched_amount does not exist
Error context:
View n/a
[view_id: n/a, xml_id: n/a, model: n/a, parent_id: n/a]

Similarly, create a new Supplier Payment for a vendor with an open PO. On the Debits tab, click on one of the line-items. You will get the following error:
ValueError: Field payment_group_matched_amount does not exist
Error context:
View n/a
[view_id: n/a, xml_id: n/a, model: n/a, parent_id: n/a]

For either of the above I can post the full error if it helps.

I have limited coding experience, so I was unable to track down which .py was causing the error, but if someone wants to point me in a direction I'm happy to do some investigation. I'm happy to help!

Very important: Thank you for this module!
