Don't expand defined types

[schani]

This input will produce a schema where the type Result is not used in Response:

export type Result = { key: string };

export type Response = {
    items: { [name: string]: Result };
};

This is the output:

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "definitions": {
        "Response": {
            "properties": {
                "items": {
                    "additionalProperties": {
                        "properties": {
                            "key": {
                                "type": "string"
                            }
                        },
                        "type": "object"
                    },
                    "type": "object"
                }
            },
            "type": "object"
        },
        "Result": {
            "properties": {
                "key": {
                    "type": "string"
                }
            },
            "type": "object"
        }
    }
}

It works with interfaces:

export interface Result { key: string }

export interface Response {
    items: { [name: string]: Result };
}

I'm pretty new to using this library, but wouldn't --aliasRefs solve this issue?

[HoldYourWaffle]

Tested it, this is not fixed by --aliasRefs, although I'm not sure if that's a bug or if --aliasRefs is supposed to do something else.

[domoritz]

aliasRefs only somewhat works with the approach in this library.

[HoldYourWaffle]

Yeah I noticed that... One of the main reasons why I think we should switch to the AST approach (vega/ts-json-schema-generator#101)

[domoritz]

Yep, that's why I switched to the different approach for Vega-Lite.
