ICE-8719 Fixed delay calculations. Added callback invocation of the session expired callbacks after the warning interval has elapsed as well, this way the session expired popup will show up as expected. Also, introduced test for the existence on form.elements before trying to clear their callback, IE return null instead of empty array when form elements do not exist.
