Revert "Make mail-extract-address-components return the user name more"

This reverts commit 8b50ae8b2284b5652c2843a9d0d076f4f657be28.

According to tests in bug#27656 by OGAWA Hirofumi, this patch
led to wrong results when binding

(dolist (addr '("Rasmus <rasmus@gmx.us>" "Rasmus <mbox@gmx.us>"))
  (dolist (ignore-single '(t nil))
    (dolist (ignore-same '(t nil))
      (let ((mail-extr-ignore-single-names ignore-single)
	    (mail-extr-ignore-realname-equals-mailbox-name ignore-same))
	(message "%s" (mail-extract-address-components addr))))))

in combination.
