Addons: build.current API response fix (#11068)

When _not sending `url=` parameter_, we were returning the lastest build by date,
but we need to filter it by `state=finished` and `success=True` in the same way
as we are doing when sending the `url=` parameter.

I found this while working on readthedocs/addons#88
