[Distutils] Can't upload sdist: "File already exists"

There is a fairly new restriction that you can only have *one* sdist per release now. That should not apply at all to Wheels and if it is, then it is a bug. I can’t reproduce this issue though, so I’m going to guess there was some bit of confusion about exact errors here. If someone actually cannot upload 1 sdist + N wheels, please leave the state as is and tell me.
