Make new regression tests for INCLUDE stable.

Browse source 
The regression tests included the oid of the hypothetical index.  Since the
hypothetical Oid generator was introduced, the sequence of generated Oids is
somewhat stable for a given PostgreSQL major version, but is defenitely not
across multiple major versions.
