Disabling mysterious CI failures

[therealryan]

Our selenium-based tests started throwing failures today. We've made no changes to the project and can't replicate the failure locally.

We've tried:

• Testing on a windows-os CI machine. This had no effect - the windows testing shows the same failure as linux
• Downgrading the chrome version to what should have existed for previous successful runs. This had no effect.

It really sucks, but this PR disables the tests in question in CI runs. We can still run the tests locally.

I've raised #975 to fix this in the future, but right now:

• these failures are blocking PRs that we probably want
• local testing shows that the functionality being exercised does still work.
