Remove ref

[BridgeAR]

This removes ref for now as it will fail on all citgm runs currently
due to the testing framework not being compatible anymore. There are
two open PRs to fix this and as soon as either is merged, I'll open
a new PR to add ref back.

Why not "skip": true?

Seems like the actual breaking change was mocha (ref has * in the package.json and mocha released a new major). It seems an unintentional breaking change and now ref passes again on CITGM, so I'll close this.
