Description of issue:

introduced a modal to allow a user to delete empty holdings resulting from a changed holdings location in Receiving.

Testing in Orchid, Poppy, and Quesnelia Bugfests show that the modal is no longer appearing when a changed receiving location leaves another holdings record empty.

Reproduction steps:

1. Log in to using folio_admin permissions.

2. In the Inventory app, click Actions > Import and import LCCN 2019012345 using the Library of Congress target.

3. From the new instance, select Actions > New order.

   1. Vendor = Amazon

   2. Order type = One-time

4. Add a POL.

   1. Location = Acq Mono

   2. Inventory interaction = Instance, holdings, item.

5. Open the order.

6. On the POL, click Actions > Receive.

7. On the Expected piece, click Actions > Receive.

8. Select the piece and update the holdings location to another location (not the one selected in step 4a).

9. Receive the piece.

Expected results:

A modal appears indicating that the original holdings record is no longer associated with items. User can select to keep or delete the empty holdings.

Actual results:

No modal appears. The item is moved to the new holdings record and an empty holdings record remains on the instance, associated with the location on the POL.
