TranslationFieldFilter does not respect setCondition

Subject

When using GlobalSearch, filters are built with OR condition:

if ($filter->getOption('global_search', false)) {
    $filter->setCondition(FilterInterface::CONDITION_OR);
    $datagrid->setValue($filter->getFormName(), null, $term);
    $found = true;
 }

however, TranslationFieldFilter applies andWhere explicitly: https://github.com/sonata-project/SonataTranslationBundle/blob/2.x/src/Filter/TranslationFieldFilter.php#L56

It should respect $condition and act accordingly. Should I PR that?
