Remove test_aboba: duplicate of test_deserialization_simple_into_python

test_aboba exercised ("INT2", 2, 2) — a plain int round-tripping through an
INT2 column. That case is already covered twice in the parametrized
test_deserialization_simple_into_python: ("INT2", SmallInt(12), 12) and
("INT2", 12, 12). Adding a third plain-int/INT2 variant adds no new behaviour
under test.

Beyond redundancy, test_aboba had a latent hazard: it used the hard-coded
table name "for_test" instead of the UUID-suffixed name the parametrized test
generates, making it unsafe to run in parallel with several other tests in
this file that share that same name.
