Markus Armbruster 4b2fc7dbc4 qapi tests: Elide redundant has_FOO in generated C 
The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with.  Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step.  This is the step for
tests/qapi-schema/qapi-schema-test.json.

Said commit explains the transformation in more detail.  The invariant
violations mentioned there do not occur here.
