[BUG] we can update multiples entities in update by ID

[iariasleon]

We have two entities with the same entity_id:
ex:

POST http://<host>:<port>/v2/entities
Fiware-Service: happy_path
Fiware-ServicePath: /test
{"type":"room_1", "id": "room_10", "my_attr": "34"}

POST http://<host>:<port>/v2/entities
Fiware-Service: happy_path
Fiware-ServicePath: /test
{"type":"room_2", "id": "room_10", "attr_test": "45"}

And try to update an entity by ID

POST http://<host>:<port>/v2/entities/room_10
Fiware-Service: happy_path
Fiware-ServicePath: /test
{"new_attr": "14"}

Both entities are updated:
ex in mongo:

{ "_id" : { "id" : "room_10", "type" : "room_1", "servicePath" : "/test" }, "attrNames" : [ "my_attr", "new_attr" ], "attrs" : { "my_attr" : { "type" : "", "creDate" : 1441095072, "modDate" : 1441095072, "value" : "34" }, "new_attr" : { "value" : "14", "type" : "", "creDate" : 1441095097, "modDate" : 1441095097 } }, "creDate" : 1441095072, "modDate" : 1441095097 }

{ "_id" : { "id" : "room_10", "type" : "room_2", "servicePath" : "/test" }, "attrNames" : [ "attr_test", "new_attr" ], "attrs" : { "attr_test" : { "type" : "", "creDate" : 1441095085, "modDate" : 1441095085, "value" : "45" }, "new_attr" : { "value" : "14", "type" : "", "creDate" : 1441095097, "modDate" : 1441095097 } }, "creDate" : 1441095085, "modDate" : 1441095097 }

In this case the response expected:
Status: 409 Conflict

{
error: "TooManyResults"
description: "There is more than one entity with that id. Refine your query."
}

Due to mongoBackend implications, @fgalan could be the best candidate for assigning this.
