Usage in AP broken (but not the expected break)

cc @ghallett @jconnaug

When trying to use unreleased Franklin in AP to test changes, I'd expect to receive something akin to:

errors=[
  "Job used unreleased Franklin build - failing"
]

from the lb-conda default merging job.

E.g.: We do get a failure, e.g. in ew_projects_run3.18607:

However, we get no clear indication of any reasoning/errors in the log.

Once Franklin is released, the log looks identical but it now passes.
