When a PrefabDOM was taken from a PrefabDocument the Instance would continue to have the data from the original Prefab, which means they'd no longer be in sync as the Prefab would be empty. This was fixed by resetting the Instance so they're both clear. Signed-off-by: AMZN-koppersr <82230785+AMZN-koppersr@users.noreply.github.com>
