bundlerepo: enforce the requirements declared by the underlying repository
Previously, `hg log -r 'bundle()' -R bundle.hg` was failing for me when run from
source, complaining about an unknown parent, when the system installed `hg`
didn't. Some debugging showed the index was 0 length. It turned out that I
didn't have the C extensions compiled, which a simple `hg log -r .` was able to
indicate. The problem being that the RequirementError got handled by RepoError,
which uses an empty directory as a fallback to process the bundle.
