server: Add regression tests for hasura/graphql-engine#7172

In hasura/graphql-engine#7172, an issue was found where under certain conditions a JSON field from Postgres would be parsed as a GraphQL input object, which is not possible in general, and also unnecessary. Luckily, this was already fixed by the time `v2.0.6` got around, presumably thanks to 4a83bb1834. This adds a regression test.
