round-trip: converting back to a normal (non-largefiles) repo with
"lfconvert --to-normal" should give the same as ../bigfile-repo.  The
convert extension is disabled to show config items can be loaded without it.

largefiles are not cached in the converted repo's local store by the conversion
process.
