restore-file doesn't work on Enterprise Server #9938

Description

After clicking "discard changes" on a PR, Expected ``absolute`` to be "user/repo:branch", got "" gets thrown in in pr-branches' parseReferenceRaw function.

How to replicate the issue + URL

I haven't tested this on github.com. I can, if you'd like, though I suspect it works just fine. This is on GitHub Enterprise Server 3.21.3. I don't know the level of support provided for GHES (probably best-effort), but let me know if there's any useful debugging info I can collect.

It looks like the HTML structure diverged from what's expected, given that absolute is an empty string, though I haven't done too much digging.
