Reason for closure not removed from POL when reopened

Overview: Some pending and open POL are displaying when filtering by 'reason for closure' because the data has not been cleared

Steps to Reproduce:

1. Log into some FOLIO environment as User X
2. Click on PO
3. close po for any reason
4. Reopen that PO
5. Filter POs by the 'reason for closure' you used for the PO

Expected Results: The open POL does not appear in search results because it may confuse the user as to why it is currently open and not displaying a reason for closure

Actual Results: POL displays in filter results even though order is open and displays no reason for closure.

NOTE: It seems we are just not removing the reason for closure when the order is reopened.
