The $statusSql double-quoted string contained '%"status":%' which caused
PHP to terminate the string at the inner double quotes, resulting in a
parse error (unexpected identifier 'status') on the beta server.
Also cleared stale stats cache that stored by_assignee in old name=>count
map format instead of the current array-of-objects format.
