[Lens] Pinned filters not applied when coming from different app

[mbondyra]

Summary

Fixes #73012
The bug was caused by the fact that the state update only happens on updates from observable:

 const filterSubscription = data.query.filterManager.getUpdates$().subscribe({
      next: () => {
        setState((s) => ({ ...s, filters: data.query.filterManager.getFilters() }));
        trackUiEvent('app_filters_updated');
      },
    });

We do run data.query.filterManager.setAppFilters([]) on start and then data.query.filterManager.setAppFilters(savedObject.state.filters) and on document load, but if there was no appFilters in previous app, we set up the appFilters to the same value as before, and so next won't be ever run, so the state won't be synchronized.

If lens saved object has some app filters, the bug is not reproduced even without this fix.
