design:paramtypes does not work with object assignment

[Jeffrey Borg]

Been using type-graphql and came across this issue

Here is a sample class which returns a void type for the argument

class Demo {
  @Method()
  test(@Args(): { destructedProp } : ClassType) {}
}

This sample works

class Demo {
  @Method()
  test(@Args(): arg : ClassType) {}
}

It seems the param.type here https://github.com/leonardfactory/babel-plugin-transform-typescript-metadata/blob/master/src/metadata/serializeType.ts#L25 is ObjectPattern and this results in returning voidZero()
