GET retrieves DID's destination link

Given I am authenticated as customer K0002
And there is a queue service with id 100 and name display name and service number 345 and extension number 555
And there is a Trunk with:

baseNumber +48 (22) 123456
numberblockStart: 0
numberblockEnd: 1

And there is a DID with extension 0 assigned to this Trunk
which has:

Group with extension number 555 set as destination

When I send /api/customers/K0002/dids/0048.22.123456-0/destination
Then I should receive HTTP/1.1 200 OK
with following body:

{
  "href": "/api/customers/K0002/dids/0048.22.123456-0/destination",
  "links": [{
    "rel": "destination",
    "href": "/api/customers/K0002/targets/queue-services/345"
  }],
  "data": null
}

GET retrieves no destination link if destination is not set for given DID

baseNumber +48 (22) 123456
numberblockStart: 0
numberblockEnd: 1

And there is a DID with extension 0 assigned to this Trunk
which has:

No destination set

When I send /api/customers/K0002/dids/0048.22.123456-0/destination
Then I should receive HTTP/1.1 200 OK
with following body:

{
  "href": "/api/customers/K0002/dids/0048.22.123456-0/destination",
  "links": [{
    "rel": "destination",
    "href": "/api/customers/K0002/targets/NO_ACTION"
  }],
  "data": null
}
