Extend omnisharp test to cover more project types

Omnisharp needs separate tasks/dlls for separate project types. Testing
with just a `console` project is not sufficient to verify that all
project types work. We need to test with each project type that we care
about to make sure it works.

See dotnet/source-build#2006 for more
information.
