[5.0.8] Looks like upgrade from V4 does not clean up the old '_Status' files...

Hello,

Our PHP-FPM error log is filling up with the following:

Because of the underscore (in '_Status') it appears to me that this is an old V4 file that should have been removed during the upgrade.

More to the point - how and why is this file being called? Of course, on our system there were lots of status messages created under V4 - my presumption (possibly incorrectly) is that these old Statuses somehow trigger a request to display the status message?
