Incoherent batch behavior when performing batch all_elements and specifying id's at the same time

When performing a batch action with a confirmation page, there is an inconsistency what the user will get in the confirm vs what sonata will really do.

Steps to reproduce

Take any admin list with a couple of records, select one of them, then select "all records" checkbox by the batch actions and click any batch action with a confirmation page (batch delete will do). The confirmation page will show 'you are about to delete all elements. Proceed?'

This is not surprising, as the template admin-bundle/src/Resources/views/CRUD/batch_confirmation.html.twig states:

<div class="box-body">
                {% if data.all_elements %}
                    {{ 'message_batch_all_confirmation'|trans({}, 'SonataAdminBundle') }}
                {% else %}
                    {% trans with {'%count%': data.idx|length} from 'SonataAdminBundle' %}message_batch_confirmation{% endtrans %}
                {% endif %}
            </div>

so check if the 'all elements' checkbox is checked, if yes - message_batch_all_confirmation

but in the controller admin-bundle/src/Controller/CRUDController.php

we have

    public function batchAction(Request $request): Response
    ...
  
        if (\count($idx) > 0) {
            $this->admin->getModelManager()->addIdentifiersToQuery($this->admin->getClass(), $query, $idx);
        } elseif (!$allElements) {
            $this->addFlash(
                'sonata_flash_info',
                $this->trans('flash_batch_no_elements_processed', [], 'SonataAdminBundle')
            );

            return $this->redirectToList();
        }

        return \call_user_func($batchActionExecutable, $query, $forwardedRequest);
    }

so the controller adds the identifiers even if all elements is selected, and this implies that a sequence of AND and OR statements is added to the query.

Expected results

I would expect, that sonata will delete all elements, as the confirmation page stated that it will do so

Actual results

Sonata will delete only the one selected element

The question is - should Sonata prioritize all elements and the controller should be corrected, or should idx be prioritized and the confirmation page should be addjusted

I'm happy to help with the fix, but a decision needs to be made

Take any admin list with a couple of records, select one of them, then select "all records" checkbox by the batch actions and click any batch action with a confirmation page (batch delete will do). The confirmation page will show 'you are about to delete all elements. Proceed?'

I consider it should delete all elements then, so controller should be corrected.

Do you mind a PR @pietaj ?
