bookmarks: drop filterredrevs cache invalidation no longer needed

In the previous patch we invalidate the cache of visible revisions when the
dynamic blockers when they are requested and the dynamic blockers have changed.

This allows us to centralize the cache invalidation logic for that case and
removes the need to invalidate the cache when an actual dynamic blocker occur.

We were invalidating the cache for bookmarks and since it is no longer needed,
we remove the cache invalidation.
