tests/qapi-schema: Improve union discriminator coverage

A union's 'discriminator' must name one of the common members.
QAPISchemaVariants.check() looks it up by its c_name(), then checks
the name matches exactly (because c_name() is not injective).

Tests union-base-empty and union-invalid-discriminator both cover the
case where lookup fails.  Repurpose the latter to cover the case where
it succeeds and the name check fails.
