Bad tempfile path

Looks like there is an extra / in the tempfile path.

$ asdf install elixir 1.3
/var/folders/hn/2gyswljs27179p4ddtdvrqkc0000gn/T//elixir-precompiled-1.3.zip

Turns out this is a just a really confusing secondary error. The correct command is asdf install elixir 1.3.0. Maybe we should validate the version number? Also it would be good to fail faster, so we don't try to unzip a bogus file.

Thanks for discussing this error here: I had the same today with Erlang when trying to run asdf install erlang 20 instead of asdf install erlang 20.0 and was puzzled until I found this post… 👍

This also happens for new Elixir releases, when the compiled file isn't ready yet. That seems to be the case with 1.8 RC1 right now.

@kamidev yep, just came across that issue with 1.8 RC1.

I do not think #29 fixed this issue.
