currently Laravel is not happy with the prepared statement:

$m->saveMetrics($w)

   Illuminate\Database\QueryException  SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?), '%Y%m%d%H%i%S')) AS sum_actions

We talked about how we could "properly" test this and concluded that this is one of the main weaknesses of this approach. We're so tightly bound to the implementation / layout of mediawiki's private dbs that this isn't really possible to seed with good test data. Hence why this just lives as a null

tests fixed!
