Restore disabled entities to the statistics table

[karwosts]

Proposed change

I want to make a case for a revert of #10677, which I don't quite understand the reasoning for. This PR will remove the filter for disabled entities in the statistics table, causing them to again be shown (with a corresponding FIX ISSUE).

If user has a disabled entity, and it still has data recorded in the statistics table, I think the user would like the opportunity to be able to clean that up to minimize unnecessary data in the table. Currently once an entity is disabled, it's records now remain forever orphaned in the table and you can't delete them.

I asked Tom (author of the original issue that spawned the original PR), and he said he's fine with reverting it now that he understands that if he "fixes" the issue, the entity will go away from the table. I guess he originally thought all disabled entities would always appear in the table, which is not the case.
