Invalid notification on PATCH Entity, updating attributes

[kzangeli]

When updating an attribute A1, using PATCH /entities/*/attrs, the notification sent contains the old attribute A1.
But not only that, the notification also contains an extra, expanded copy of other attributes of the entity ...
Tests done using the functest ngsild_patch_entity_attr_with_subscription.test:

Entity Creation:

payload='{
  "id": "urn:ngsi-ld:entity:E1",
  "type": "T",
  "A1": {
    "type": "Property",
    "value": "A1 Step 1",
    "PP1": {
      "type": "Property",
      "value": "A1::PP1 Step 1"
    }
  },
  "A2": {
    "type": "Property",
    "value": "A2 Step 1"
  }
}'
orionCurl --url /ngsi-ld/v1/entities -X POST --payload "$payload"

Update of A1:

payload='{
  "A1": {
    "value": "A1 Step 3",
    "type": "Property"
  }
}'
orionCurl --url /ngsi-ld/v1/entities/urn:ngsi-ld:entity:E1/attrs -X PATCH --payload "$payload"
