bst checkout fails to find the correct artifact in non strict mode

Summary

Steps to reproduce

Not sure it is reproducible, but here is what happens with me. I'm using gnome-build-meta commit 6f538b0529b288b0af257906f0f2b11a34a8e5fb, and have the following in my config.

projects:
  freedesktop-sdk:
    strict: False
  gnome:
    strict: False
> bst build vm/image.bst
> bst checkout vm/image.bst # => error
> bst --strict build vm/image.bst
> bst checkout vm/image.bst # => error
> bst --strict checkout vm/image.bst # => works
