fix: do not try to inflate a fresh lockfile

when running an updateAll, we use Shrinkwrap.reset() to empty and reset
the lockfile metadata. however, due to _inflateAncientLockfile having a
check on meta.originalLockfileVersion, we need that property to be set
on a freshly reset lock so that _inflateAncientLockfile knows it has no
work to be done.
