date_detection not working with not_analyzed fields

Elasticsearch version: 2.2.0

JVM version: Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

OS version: OSX 10.11.1

Description of the problem including expected versus actual behavior:

If you enable both date_detection: true and index: not_analyzed in a dynamic template, dates are not detected.

Steps to reproduce:

1. Create a template with a PUT to _template/reproducebug and the following body (date_detection: true and index:not_analyzed):

{
    "template": "*",
    "mappings": {
        "_default_": {
            "date_detection": true,
            "_all": {
                "enabled": false
            },
            "dynamic_templates": [
                {
                    "template1": {
                        "mapping": {
                            "index": "not_analyzed",
                            "type": "{dynamic_type}"
                        },
                        "match": "*"
                    }
                }
            ],
            "properties": {
                "msg": {
                    "type": "string",
                    "index": "analyzed"
                }
            }
        }
    }
}

1. Index the following document, that contains a ISO8601 date: {"foo":"bar", "time":"2016-03-08T09:52:09.097Z"}
2. Check that the field time is indexed as a not_analyzed string.

Provide logs (if relevant):
No relevant logs.

You're running into this: #2401

If you change your template to use "match_mapping_type": "*" instead of "match": "*" it will work

Yes, it worked. Thanks.
