Pass created revision to TitleMoveComplete hook

Pass created revision to TitleMoveComplete hook

The EventBus extension needs to forward the created (null) revision ID as
part of the page move event.  Looking this value up when the hook fires is
problematic, because without a connection to the master DB the query might
very well return nothing (if it races in before the entry is replicated to
the slave).

This changeset passes the newly created Revision on to the hook so that it
doesn't need to be queried separately.
