ESDEV-2145 Fix bug #5809: Session ID Disclosure

Adding addShopHost() method, which adds shop host to the start of the url if it is not set.
Also reverting processUrl() so that it would only add parameters to url, because there are other places which uses this method like that.
Removed deprecated code marked in 5.0.x : oxUser::checkPassword()

Adding shop host to url if needed, as it was removed from oxUtilsUrl::processUrl().
Removed deprecated code marked in 5.0.x : oxUser::checkPassword()
