Correctly set t_self for heap tuples in expand_tuple

Commit 16828d5c0 incorrectly set an invalid pointer for t_self for heap
tuples. This patch correctly copies it from the source tuple, and
includes a regression test that relies on it being set correctly.

Backpatch to release 11.

Fixes bug #15448 reported by Tillmann Schulz
