Before this commit, error handling would not work for non s2s payment acquirer since it would always check for `o_payment_add_token_acq_[id]` in the DOM but this is only present for s2s acquirer. Non s2s acquirer got `o_payment_form_acq_[id]` in the DOM. Now, we retrieve the correct DOM element depending if s2s is enabled for this payment acquirer or not. task-1825701
