Today the rpm-ostree test suite uses `refs --create` to save
commits. I think this is a legitimate use case, and other
people may be doing something similar.
On the other hand, I think we should probably be changing the rpm-ostree test
suite to create "unbound" commits. But let's be maximially compatible here since
we hit a real-world case where something needed to change.

Test various pieces of core and command line utility functionality
relating to the newly-introduced concept of collections. Mostly focussed
around the find-remotes utility, and around handling of collection–refs.
