util.jsonschema: Fix handling of `false` as schema Schemas can be either a boolean or a table (object) but since it only checked for truthiness, the case of `false` would be handled incorrectly. There seems to be no tests that cover `then` and `else` being `false`, only a couple that check the `if` keyword.
