Remove problematic discovery test

[mjcarroll]

This test has recently appeared to fail, we have some on-going diagnosis in #335. In the meantime, I think it makes sense to disable to get CI back into a reasonable state.

Can we just disable the test on the platforms where it fails, instead of removing it?

We can, as it turns out, we don't have a macro to disable a test only on Linux, I suppose it's never been needed before?

[mjcarroll]

New warnings on windows are to be addressed elsewhere.

Would you be able to backport this to Citadel and merge forward to Fortress? Thanks!
