The upstream smoke tests include an omnisharp test.

I rather remove this than fix it and continue to maintain it.

@omajid wdyt?

@omajid @nicrowe00 anyone opposed to removing this test?

[nicrowe00]

The upstream smoke tests include an omnisharp test.

If that's the case then I have no issue with removing it.
