Properties not defined in JSON schema cause "TypeError"

Expected behavior

Properties not defined in JSON schema can be added if it is allowed by the schema.

Actual behavior

Any property added to JSON and not described in JSON schema causes error in console: TypeError: can't convert null to object

Steps to reproduce the behavior

1. Create JSON schema:

{
  "type": "object",
  "title": "Error: Properties not descibed in schema cause error",
  "description": "Create schema for one property, then add another one",
  "additionalProperties": true,
  "required": ["name"],
  "properties": {
    "name": {
      "type": "string",
      "title": "name"
    }
  }
}

1. Load the schema into the JSON Editor, then try to add any property.
2. The new property will be successfully added, but there will appear above mentioned error in browser console.

See https://jsfiddle.net/9kcyL7g3/1/ (look at the browser console, too). There is a problem with an option: remove_empty_properties: true
