Describe the bug:

When defining actions for a rule, if a filter with AND or OR is created in the AddFilterPopover (inside `If alert matches a query') saving the form throws an error.

Steps to reproduce:

1. Go to Rules and try creating a new rule of any type
2. Add an action to the rule
3. Check the option If alert matches a query
4. Click the + icon to add a filter
5. Create a filter in the popover
6. Click AND or OR
7. Create another filter
8. Click Add filter
9. Try saving the rule
10. Confirm an error is displayed in a popover## Expected behavior:

No error should be thrown in the scenario described above and the rule should be saved successfully.

Screenshots:
