fix(unified_search): Maintain non-provider filters when loading more results

Maintain existing non-provider filters (like date and person filters) while
loading more results for a specific provider.

This now works as the provider data passed to the `newResults` array after search
is built dynamically and not manually, the result of a manual build was that the
`provider.filters` properpy which is used in the `find` method was being left out
in the providers pushed into the results array.

Fixes #52081
