I think the config option needs to be extensions.refsBackendType, too,
per the logic in 00a09d5 (introduce "extensions" form of
core.repositoryformatversion, 2015-06-23). And I guess it needs to bump
core.repositoryformatversion to "1".

I think also, strictly speaking, the extensions.refsBackendType option
should be ignored if core.repositoryFormatVersion is not "1". In
practice, it probably makes more sense for the code to error out in that
case because it is likely the result of a bug.

Note that if the user explicitly chooses the "files" backend, it would
be preferable to leave "core.repositoryFormatVersion" at "0" (assuming
that no other extension is being used) and leave
"extensions.refsBackendType" unset. This approach creates a repository
that is compatible with older clients that don't know about
refsBackendTypes.
