Paket bootstrap fails when switching OSes

[Kovács Ádám]

I edit my repo from Windows and also from Ubuntu. When I try to build after switching OS, paket.bootstrapper.proj tries to install paket but dotnet tells it already exists. I modified paket.bootstrapper.proj so no it's working. You can add to the repo if you will.

Can you submit this as a PR? Thanks!

Done! Check task/variable names. I just typed what jumped out of my mind. They might be not the best.

Closing as this was fixed by PR #6.
