Title: [4.2] HHVM fixes for travis

Allow hhvm failures atm, and added nightly so we can see when facebook fix the issue.

I've made an issue on the hhvm repo: https://github.com/facebook/hhvm/issues/3320, but I'd hope the team are already aware of this issue anyway since they have automated framework tests.
