Try

...
(require 'trace)
(trace-function 'do-after-load-evaluation)
(custom-set-variables ...)
(untrace-function 'do-after-load-evaluation)

and see if there is a difference in the *trace-output* buffer when you
call package-initialize first.

Maybe also do (mapc #'require '(image-file time completion elec-pair
ido avoid savehist paren)) to get the known loads (which I see listed
in your output above) out of the way.
