Saved filter not added to dropdown if not applied

[urs-beeli]

Description

In the filter dialog I can save the current filter criteria by clicking on the "save" button. After entering a name and clicking "OK", a confirmation dialog tells me that the filter has been saved.

If I then click "Apply", the fitler is applied to my database and the saved filter is added to the dropdown in the toolbar.
However, if instead of "Apply" I close the filter dialog with "Cancel", the filter is not applied (expected behaviour) and the saved filter is not added to the dropdown in the toolbar (at least not until I restart openSAK or re-open the filter dialog and close it with "Apply", then it appears in the dropdown).

Steps to Reproduce

1. start openSAK
2. open filter dialog
3. click on "Save"
4. enter name "dummy"
5. click on "OK"
6. confirmation dialog is shown, close it
7. close filter dialog by clicking on "cancel"
8. open filter drop-down in menu bar
9. the newly created filter is not shown in the dropdown
10. re-open the filter dialog
11. close filter dialog by clicking on "apply"
12. open filter drop-down in menu bar
13. now the previously saved filter appears in the drop-down

Expected Behavior

In step 7/8/9 I would have expected the saved filter to be shown
