Make the upload command follow the dependencies

By removing ‘sort’ here, the berks upload command will upload the
cookbooks using the generated dependency order instead of doing this in
alphabetical order.

As far as I can tell the extra ‘sort’ here is purely cosmetic, but we
run a (to be open sourced next week) tool called Chef-Guard that does
some additional checks in front of your Chef server which actually
needs the cookbooks to arrive in the correct order (in terms of
dependencies).

I know you just released a new version half a day ago, but as we are
now doing our final tests with Chef-Guard working towards a first
release it would really awesome if this can make it in a new release as
soon as possible.

Thanks!

If there are any questions or concerns, just ping me so I can explain
more about the use case.
