Actually, `isearch-forward' is not skipped in either case.

In the case of `bar', there is no problem: just follow through with
query-replacing (ending it when you are done), and you will see that you enter
Isearch normally. 

The problem is that in the case of `foo', Isearch is entered but more or less
immediately ends.  I did not bother to step through the debugger or study the
code to see why.  Perhaps someone will do that and reply.

But here is something that works for `foo':

(defun foo ()
  (interactive)
  (isearch-mode t nil nil t nil)
  (call-interactively #'query-replace))
