Fix refusing HTTP connections ( #1274 )

[JulioJu]

See especially #1274 (comment) and the work with @nickspoons

I can confirm that copying the files listed in DeleteUnnecessaryAssemblies in build.cake from bin/Debug/OmniSharp.Http.Driver/net461/ to artifacts/publish/OmniSharp.Http.Driver/mono results in a useable OmniSharp-roslyn server which responds to HTTP requests and can therefore be used by OmniSharp-vim.

Deletion of this files are added in the commit b1e533c named "Build: Create 'PublishMonoBuilds' target" by @DustinCampbell committed on Aug 3, 2017

The first release with the deletion of this files was 1.23.0 (https://github.com/OmniSharp/omnisharp-roslyn/releases/tag/v1.23.0).

@rchande as you are very active here, I ask you what you think about that :-)

I think this change should be pretty minor. Now that we've discussed what is really happening here. Thanks @JulioJu . Sorry for the delay!
