Stop sending loan notices with triggers "Loan due date/time" and "Item aged to lost" after loan has closed

Overview:

Some institutions are inconsistently still receiving loan notices, even after the loan has closed.
These are the affected settings:
-  Notice template category = Loan
-  Notice policy triggers = Loan due date/time  +  Item aged to lost

Steps to Reproduce:

1. Configure overdue notices to be sent after an item is overdue as recurring
   • Template
   • Policy
   • Circ rules
2. Check out an item to user that matches the above configuration
3. Check in the item

Expected Results: The user would not receive any overdue notices

Actual Results: User continues to receive overdue notices even after the loan is closed

Additional information 25 May: 

• We discussed this ticket amongst the Circ POs on 24 May, and agreed on the following: Sorry you are not able to replicate this, we believe this has to do with the tiny volume in the test environments. We still believe this bug is real.
• What we want to achieve is: 
  --  WHEN a loan closes,
  --  THEN remove from the queue all scheduled notices with the following triggers: Loan due date/time + Item aged to lost : In effect, make this part of the loan closing process. 
• Brooks strongly suggested that, to this effet, CIRC-739 should be revisited, 1) because customers are actually experiencing issues related to this, 2) because the tech. conditions have changed since then.

NOTE: Both this issue and https://issues.folio.org/browse/CIRC-1504 might possibly be solved by this old ticket https://issues.folio.org/browse/CIRC-739, suggested a few years ago but it was decided against.
