schemaPath in error in referenced schema depends on the reference

[epoberezkin]

JSON Schema (please make it as small as possible to reproduce the issue):

{
  "properties": {
    "a": { "$ref": "int" }
  }  
}

int:

{
  "id": "int",
  "type": "integer"
}

Data (please make it as small as posssible to reproduce the issue):

{ "a": "foo" }

Your code (please use options, schema and data as variables):

ajv.addSchema({
  "id": "int",
  "type": "integer"
});

var validate = ajv.compile({
  "properties": {
    "a": { "$ref": "int" }
  }  
});

validate(data);

See code

Validation result, data AFTER validation, error messages:

Result: false

errors:

[{
  "keyword":"type",
  "dataPath":".a",
  "schemaPath":"int/type",
  "params":{"type":"integer"},
  "message":"should be integer"}
]

What results did you expect?

schemaPath should be "int#/type" (if parent schema has {$ref:'int#'} it will be as it should).
