Title: Refactor done() to apply args given, so as not to allways call with 2nd ...

...param, as this messes with async.js auto.

Before the fix to pass on a 2nd parameter sequelize would work perfectly well with async.js
However know, atleast if using a custom event emitter inside an auto call, the result will come out [result, undefined] instead of just result, which is undesireable.
