Question:
Orion CB saves device with 'entity_name' value in 'id' field

Description:
I'm trying to develop IoTA with lazy attributes. And found that Context Broker saves device 'entity_name' field in 'id', so when CB makes request for lazy attributes, IoTA can't found device with such id.

With purpose to create device entity I make this request to IoTA:

'devices': [{
'device_id': 'idSensor14',
'entity_name': 'nameSensor14',
'entity_type': 'anysensor',
'attributes': [

],
'lazy': [

]
}]

Then if we request entitites list in CB ('v2/entities/') we discover:

{ "id":"nameSensor15",
"type":"anysensor",
"t":{"type":"celsius","value":"","metadata":{}}}

It seems that CB saves device with wrong id. This is request for lazy attributes:

data = {
"entities": [

,
"attributes": ["b"]
]}

And this is error in IoA log:

op=IoTAgentNGSI.ContextServer | srv=myhome | subsrv=/sensors | msg=Query error [DEVICE_NOT_FOUND] handling request: No device was found with id:nameSensor15

If delete entity_name from registration request, then CB will use device id = 'anysensors:idSensor14'. My Orion version is 1.7.0, and iotagent-node-lib version is 2.5.1.
