Geo: Does not apply selective sync restrictions while counting registries on the tracking database

What does this MR do?

Does not apply selective sync restrictions while counting registries on the tracking database due to a bad performance while retrieving node status. The changes in this MR put back the old behavior where we use the tracking database as a single source of truth for these counts when selective sync is enabled or not.
