Display snapshots with only releases (or a release as HEAD branch)

15:15:56 <+vlorentz> anlambert: We think we found an issue in swh-web: https://forge.softwareheritage.org/source/swh-web/browse/master/swh/web/browse/snapshot_context.py$562 returns None when the HEAD branch is a Release (or alias to Release) instead of a Revision (or alias to Revision) 15:16:47 <+vlorentz> so we get stuff like this on all snapshots generated by package loaders >= 1.0.0: https://webapp.staging.swh.network/browse/origin/directory/?origin_url=https://www.npmjs.com/package/chloe 15:17:23 <+vlorentz> even though they work fine via the API 15:17:51 <+vlorentz> what do you think would be the right fix for this? 15:17:53 <+vlorentz> ardumont: ^ 15:18:05 <+ardumont> context: in staging, we "released" the "make the loader package build synthetic release (and no longer revision ones)" 15:18:22 <+ardumont> (well loaders) 15:19:18 <+ardumont> $1206 for some dataset to reproduce
