2018-10-08 13:05:29 ef11eb2e [app] [I] Completed 500 Internal Server Error in 146ms (Views: 0.8ms | ActiveRecord: 15.7ms)

How reproducible:

100%

Steps to Reproduce:
1. create apiuser and assign it to organization B
2. have compute resouce in organization A
3. have compute profile with id 1 associated with compute resource from previous step
3. curl -X GET -u apiuser:changeme -H "Accept:application/json" https://$(hostname)/api/compute_profiles/1

Actual results:

{
"error": {"message":"ComputeAttribute#provider_friendly_name delegated to compute_resource.provider_friendly_name, but compute_resource is nil: #<ComputeAttribute id: 1, compute_profile_id: 1, compute_resource_id: 1, name: \"1 CPUs and 1 GB memory\", vm_attrs: {\"cpus\"=>\"1\", \"memory\"=>\"1073741824\", \"nics_attributes\"=>{\"0\"=>{\"type\"=>\"network\", \"network\"=>\"#prov_private0\", \"bridge\"=>\"public-bridge\", \"model\"=>\"rtl8139\"}}, \"volumes_attributes\"=>{\"0\"=>{\"pool_name\"=>\"provisioning\", \"capacity\"=>\"8G\", \"allocation\"=>\"0G\", \"format_type\"=>\"qcow2\"}}}, created_at: \"2016-03-02 08:20:30\", updated_at: \"2018-02-28 15:28:28\">"}
}

Expected results:

error message saying that user does not have permission to access compute profile/any other reource not belonging to his org.
