bundle: prevent implicite bundling of internal changeset
Now that the two mains source of on-disk bundle are preventing the inclusion of
internal changesets in their bundling. We can add a lower level check that
would prevent any other leakage of internal-phase changesets.
We keep the door open to some usage, like the temporary bundle using during
strip for example.
