Root ref fails to parse #201
Description
{ "$ref": "#/definitions/EmailConfig", "$schema": "http://json-schema.org/draft-07/schema#", "definitions": { "EmailConfig": { "additionalProperties": false, "properties": { "adminContact": { "type": "string" } } } } }is valid (in fact is part of the test suite here). But json-schema-to-typescript fails to resolve the ref using this library.
