Steps to Reproduce

1. Create an identity override for a given feature
2. Navigate to the feature in the environment, and the 'Identity Overrides' tab
3. Delete the identity override

Expected Behaviour

The identity override is no longer shown in the list, and the identity overrides counter against the feature is updated to correctly reflect the removal of the identity override.

Actual Behaviour

The identity override is still shown in the list and the identity overrides counter against the feature does not update until the page is refreshed.

Additional Notes

The above reproduction steps occur when using a project in our SaaS platform, which uses the Edge API (i.e. /edge-identities routes). We should also validate the behaviour in our Core API.
