repair: do not compress partial bundle if we do not keep it on disk
A partial bundle is created to temporarily save revisions > rev but
not descending from the node to strip, to be able to restore the
changesets after stripping the changelog.
Since this bundle is not kept after the strip operation, and is not
user-visible, it is not necessary and should be faster to avoid
compression.
