Initial build after template installation fails because FAKE package not restored

[rmunn]

Linux Mint 18 (based on Ubuntu Xenial), F# 4.1, .Net Core 2.1.4. To reproduce:

1. dotnet new mini-scaffold -n MyCoolNewLib -lang F#
2. cd MyCoolNewLib
3. ./build.sh

Result: Paket restore did not restore packages/build/FAKE/tools/FAKE.exe, so the build naturally failed.

BTW, when I ran mono .paket/paket.exe -v restore, Paket said, "Last restore is still up to date". So this might be a Paket bug; I'm still trying to track down why Paket thinks the last restore is still up to date when there's no packages folder at all.

The reason is because the file paket-files/paket.restore.cached exists in the template. Paket uses that file to do an early exit if there's no work to do: if the paket.lock file is identical to paket-files/paket.restore.cached, then Paket knows that there's no work to be done and does an early exit to save time.

The template should not include paket-files/paket.restore.cached so that a first run of build.sh will actually restore the necessary files.

Derp! This will be easy to fix. Thanks for the investigation!

Ok this is fixed. The only issue you'll run into is #36
