Comment (by dd32):

 FWIW, it looks like the changes here are probably correct, most of the
 $this->result should be replaced with simply $result, except in the Theme
 Upgrader where it is something else.

 At present for example, Plugin_Upgrader->upgrade() returns null for
 failures instead of the WP_Error.

 Sorry @chrisbliss18 but as you can probably tell, following some of the
 code isn't as easy as you expect at first glance.
