Remove deprecated scope handling

The `initScope` function is deprecated since ocata, so this patch
replaces it into `initAction` if it needed, or removes it.
Also, gets scope from second parameter of perform function.
Futher more, removes deprecated `scope` parameter for `modal`
function of wizard-modal-service.
