fix: update cache, even when the total is 0 (#7582)

Browse Source 
This PR fixes a bug where we wouldn't update the `useFeatureSearch`
hook's cached `total` value if the new total was `0`. The reason this
failed is that we would only update it if `data?.total`. Because `0` is
a falsy value, the check would fail.
