Problem with filtering on inner/nested column

[klahnakoski]

Example:

{
    "from": "treeherder",
    "groupby": "repo.push.id",
    "where": {
        "exists": "failure.notes.text"
    }
}

[klahnakoski]

fixed

The original problem was two columns for failure.notes.text. Only one column is now in use because of the reindex

Works with current version
