Tweaked the dummy database backend initialisation.

In order to report more comphrehensible tracebacks, remove the super()
constructor call, since passing args to object.__init__ ends badly. So some
subclassing possibilities are now removed, but it's the "dummy" backend, so
we can make some compromises.
