✨ Reassigned posts when deleting a user

Browse Source 
refs https://github.com/TryGhost/Toolbox/issues/268

 - When the user is removed our current pattern was deleting their posts. This didn't work well and created all sorts of problems
 - As a solution we now reassign any posts that are only authored by the deleted user to the owner user
 - This change also reduced the dependency on "author" field
