When the "Delete live page" feature is used, the page's children are not removed from the live system. This is due to the fact that they're recreated during import.
Steps to reproduce:
1) Turn on local staging.
2) Create a page "One" with a child page "Two".
3) Publish all pages to live.
4) Open the publish-to-live dialog again and press "Change selection". Select only "One".
5) Select "Delete live page" and publish.
Expected behavior: "One" and "Two" are deleted from live.
Actual behavior: "Two" is still in the database for the live site but has a new layoutId.
