org-todo-yesterday: Ignore `org-use-effective-time'

* lisp/org.el (org-todo-yesterday):
* lisp/org-agenda.el (org-agenda-todo-yesterday): Ignore global
`org-use-effective-time' value.

Otherwise, if `org-use-effective-time' being nil,
`org-extend-today-until' will not be considered, resulting in the
current time being used instead of 23:59 yesterday.
