References not working with EXT:container

[spoonerWeb]

          I have installed EXT:container. 

In a two column container element i have a header element. When i use "Paste after as reference", then the new reference is created as an "unused element" and not in the container after the header element.

Payload paste reference after

Payload copy after

Problem is that the information of tx_container_parent is missing. Adding the correct UID into DB and the reference is right.

Will create a PR.
