Description

Steps to repro:
1. create below entity with two reference entities in it using /entities POST rest call

{
  "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
  "id":{
    "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
    "id":"-16989787630260306",
    "version":0,
    "typeName":"ComplexEntityTestTable9u3zoazpsj",
    "state":"ACTIVE"
  },
  "typeName":"ComplexEntityTestTable9u3zoazpsj",
  "values":{
    "columns":[
      {
        "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
        "id":{
          "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
          "id":"-16989787630260309",
          "version":0,
          "typeName":"ComplexEntityTestColumn2iv0d87lrb",
          "state":"ACTIVE"
        },
        "typeName":"ComplexEntityTestColumn2iv0d87lrb",
        "values":{
          "name":"column14vqfo3ocvf13"
        },
        "traitNames":[

        ],
        "traits":{

        },
        "systemAttributes":{
          "createdBy":null,
          "modifiedBy":null,
          "createdTime":null,
          "modifiedTime":null
        }
      },
      {
      	        "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Reference",
        "id":{
          "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
          "id":"-16989787630260308",
          "version":0,
          "typeName":"ComplexEntityTestColumn2iv0d87lrb",
          "state":"ACTIVE"
        },
        "typeName":"ComplexEntityTestColumn2iv0d87lrb",
        "values":{
          "name":"column2dofzvezzh12123"
        },
        "traitNames":[

        ],
        "traits":{

        },
        "systemAttributes":{
          "createdBy":null,
          "modifiedBy":null,
          "createdTime":null,
          "modifiedTime":null
        }
      }
    ],
    "db":{
      "jsonClass":"org.apache.atlas.typesystem.json.InstanceSerialization$_Id",
      "id":"bad8c2eb-050e-4dbc-b219-92a5fe850fef",
      "version":0,
      "typeName":"ComplexEntityTestDB2dnlau6arq",
      "state":"ACTIVE"
    },
    "name":"createComplexEntityTablebllw6t3u1x123"
  },
  "traitNames":[

  ],
  "traits":{

  },
  "systemAttributes":{
    "createdBy":null,
    "modifiedBy":null,
    "createdTime":null,
    "modifiedTime":null
  }
}

2. Check the response for this POST request. Ideally first the reference entity GUID should be present in entities.created[] array.
For example:
IF table1 is created with col1 and col2 then the response object should contain entities.created["col1.GUID", "col2.GUID", "table1.GUID"] but the actual response contains in reverse order. This breaks the exisitng behavior and hence regression
