Paket: Get rid of NUnit

[matthid]

Description

Because we use Mono.Cecil and they seem to be unable to fix https://github.com/nunit/nunit3-vs-adapter/issues/366 we should get rid of it and use something that works.

Expecto? ;)

[matthid]

Personally I'd accept any PR that switches to something that works and ideally allows me to debug single tests in visual studio. Last word is on @forki however. With Nunit we already have two hacks in place and it still doesn't work :/

[forki]

As long as we don't move to xunit...

[smoothdeveloper]

Is it worth to switch away from NUnit just because the VS test runner has an issue?

I haven't got a problem with Resharper test runner, and it doesn't look like test runners in other IDE have that problem either.

Resharper doesn't seem to pick them up here, I have to run ./build.sh DotnetTest to actually run the tests ;)

I believe this issue is now fixed in the latest versions of the NUnit3TestAdapter (3.11).
