Overview: Counters of "Shared" facet options count Instances with empty Item's "Effective call number" field.
NOTE: the fix should be applied for each call number browse option

Steps to reproduce:

1. Log in into ECS Quesnelia bugfest environment as admin user.

2. Switch active affiliation to “College” (member) tenant.

3. Go to “Inventory” >> “Browse”

4. Select “Superintendent of Documents classification" browse option

5. Run any browse, ex. “Test”

6. Expand “Shared” accordion and note values in counters next to the options

7. Select “Search” tab in “Search|Browse” toggle

8. Create a new Instance:
   Click on the “Actions” >> “New local record” >> Fill required fields >> Click on the “Save & close”

9. Create a new Holdings for created Instance:
   Click on the “Add holdings” >> Fill required fields >> Click on the “Save & close” button

10. Add an Item to the created “Holdings” and select “Superintendent of Documents classification" call number type:
    - Click on the “Add item”
    - Select “Superintendent of Documents classification" in “Call number type” dropdown
    - Fill required fields (don’t fill “Call number” field)
    - Click on the “Save & close” button

11. Go to “Inventory” >> “Browse”

12. Select “Superintendent of Documents classification" browse option

13. Run any browse, ex. “Test”

14. Expand “Shared” accordion and note values in counters next to the options

Expected result: Counters of “Shared” facet options didn't change.
We shouldn’t count “Instances” with “Holdings” and “Items” with empty "Effective call number" field.

Actual result: Counter of “No” option is increased.
