Fix search result schema json

[JanneHarju]

This is started to complain about wrong schema in search result schema. Problem is with oneOf it is now #/oneOf. So #/ must be moved from child object $ref to parent like this:

"#/oneOf": [
    { "$ref": "definitions/artist" },
    { "$ref": "definitions/album" },
    { "$ref": "definitions/track" },
    { "$ref": "definitions/fan" },
    { "$ref": "definitions/label" }
  ]
