Current Behavior

Go CodecService fails to encode leaf-list data.

Steps to Reproduce

Include this test to unit test suite in sanity_codec_test.go and run it.

func (suite *CodecTestSuite) TestLeafList() {
	runner := ysanity.Runner{}
	runner.Ytypes.BuiltInT.EnumLlist = append(runner.Ytypes.BuiltInT.EnumLlist, ysanity.YdkEnumTest_local)
	runner.Ytypes.BuiltInT.EnumLlist = append(runner.Ytypes.BuiltInT.EnumLlist, ysanity.YdkEnumTest_remote)

	payload := suite.Codec.Encode(&suite.Provider, &runner)
	fmt.Printf("%s\n", payload)
	runnerDecode := suite.Codec.Decode(&suite.Provider, payload)
	suite.True(types.EntityEqual(&runner, runnerDecode))
}

Run the script

$ go test -run CodecTestSuite/TestLeafList
CodecTestSuite: TestLeafList ...
<runner xmlns="http://cisco.com/ns/yang/ydktest-sanity">
  <ytypes>
    <built-in-t/>
  </ytypes>
</runner>

Note that leaf-list data are not included to the payload
