LPS-34791

The issue with this one was that if you sent a wiki page to the recycle bin that had a child page it would throw a stack trace because the parent Title was never removed after it was sent to the recycle bin. I opted not to restore the title if you bring the parent page back from the recycle bin because it is possible for the child page to be linked to other pages or have it's title changed, so if they do bring pack the parent page it will have to manually be re-added as a child page (which can be done through edit page).
