tests/qapi-schema: Rework comments on longhand member definitions

A few old comments talk about "desired future use of defaults" and
"anonymous inline branch types".  Kind of misleading since commit
87adbbffd4 "qapi: add a dictionary form for TYPE" added longhand
member definitions.  Talk about that instead.
