Multiple descr attributes duplicates inherited template attributes

[jalmargyyk]

If a specific customer template has multiple "descr" attributes, the ripe update will fail. The reason for this seems to be duplication of status attribute and other attributes from the inherited base template.

e.g.
templates.json:

{
    "templates":
    {
        "TEST-NET": {
            "attributes": [
                {"descr": "Test Company Ltd."},
                {"descr": "Test road 1234"}
            ],
            "inherit": "base_test_company.json"
        }
    }
}

base_test_company.json:

{ "attributes": [
    {"org": ""},
    {"admin-c": "AA2-TEST"},
    {"tech-c": "AA2-TEST"},
    {"mnt-by": "TEST-NCC-HM-MNT"},
    {"status": "ASSIGNED PA"},
    {"source": "TEST"}
]}

ripe-updater tries to send the following object to ripe db:

{'objects': {'object': [
      {'source': {'id': 'RIPE'
        }, 'attributes': {'attribute': [
            {'name': 'inetnum', 'value': '192.168.0.0 - 192.168.0.255'
            },
            {'name': 'netname', 'value': 'TEST-NET'
            },
            {'name': 'descr', 'value': 'Test Company Ltd.'
            },
            {'name': 'descr', 'value': 'Test road 1234'
            },
            {'name': 'org', 'value': 'ORG-EIPB1-TEST'
            },
            {'name': 'country', 'value': 'FI'
            },
            {'name': 'admin-c', 'value': 'AA2-TEST'
            },
            {'name': 'tech-c', 'value': 'AA2-TEST'
            },
            {'name': 'mnt-by', 'value': 'TEST-NCC-HM-MNT'
            },
            {'name': 'admin-c', 'value': 'AA2-TEST'
            },
            {'name': 'tech-c', 'value': 'AA2-TEST'
            },
            {'name': 'mnt-by', 'value': 'TEST-NCC-HM-MNT'
            },
            {'name': 'status', 'value': 'ASSIGNED PA'
            },
            {'name': 'source', 'value': 'RIPE'
            },
            {'name': 'status', 'value': 'ASSIGNED PA'
            }
          ]
        }
      }
    ]
  }
