Description

Add support case for enumNames.
Spec: json-schema-org/json-schema-spec#57

We have some schemas with the following shape:

{
 "jsonSchema": {
 "type": "object",
 "title": "Datalist",
 "properties": {
 "test": {
 "type": "string",
 "enum": [ "a", "p", "b", "c", "l", "g" ],
 "enumNames": [ "Apple", "Pine[apple]", "Banana", "Cher[ry", "Lemo}n", "Grapefruit" ]
 }
 },
 "required": [
 "test"
 ]
 },
 "uiSchema": [
 {
 "key": "test",
 "title": "Datalist with named options",
 "widget": "datalist"
 }
 ],
 "properties": {
 "test": "Pine[apple]"
 }
}

This raise exception with the current implementation because we have an array of value for the titleMap;
