Broken schema since v0.91

The schema output broke for me since the addition of functions. Here’s a simple example:

export enum DurationUnit {
  Hour,
  Minute,
  Second,
}

export interface Duration {
  value: number;
  unit: DurationUnit;
}

export function durationOf(value: number, unit?: DurationUnit): Duration {
  return { value: value, unit: unit ?? DurationUnit.Minute };
}

Which used to generate:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "definitions": {
    "DurationUnit": {
      "type": "number",
      "enum": [0, 1, 2]
    },
    "Duration": {
      "type": "object",
      "properties": {
        "value": { "type": "number" },
        "unit": { "$ref": "#/definitions/DurationUnit" }
      },
      "required": ["value", "unit"],
      "additionalProperties": false
    }
  }
}

But since v0.91, this is what I get:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "definitions": {
    "DurationUnit": {
      "type": "number",
      "enum": [0, 1, 2]
    },
    "Duration": {
      "type": "object",
      "properties": {
        "value": { "type": "number" },
        "unit": { "$ref": "#/definitions/DurationUnit" }
      },
      "required": ["value", "unit"],
      "additionalProperties": false
    },
    "*": {
      "type": "object",
      "properties": {
        "value": { "type": "number" },
        "unit": { "$ref": "#/definitions/DurationUnit" }
      },
      "required": ["value"],
      "additionalProperties": false
    }
  }
}

Any idea what’s wrong?
