Use the final_oid_fn to finalize hashing of object IDs

Browse Source 
When we're hashing a value which is going to be an object ID, we want to
zero-pad that value if necessary.  To do so, use the final_oid_fn
instead of the final_fn anytime we're going to create an object ID to
ensure we perform this operation.
