main page and github checks status disagree with build page status

[trefis]

Apologies in advance for the reproduction case which is probably going to be stale somewhat soon.
Right now, when I go on https://ci.ocamllabs.io/github/ocaml/merlin everything is red, but if I pick one of the branch actively being developped (e.g. master), I can see a majority of the tests as orange and "(active)".
If indeed I click on one such test, the log ends with: "2021-01-14 14:42.43: Waiting for resource in pool OCluster".

Equally annoyingly, this PR ocaml/merlin#1238 is flagged as failing to pass the CI, however if I click on "Details", I can see no failure, only active builds.

It means something changed it opam-repository and it's doing a background rebuild. It doesn't update the status until it finishes (because usually it stays the same, and you don't want your PRs orange half the time).

Should be better once we have #175 (allow viewing previous builds).
