[4.x]: Element action buttons are not centered if the source has no exporters

[mmikkel]

What happened?

Description

#12793 improved element action buttons' visibility by increasing color contrast and centering the buttons in the index footer.

However if a source has no element exporters defined, the action buttons are not centered:

Steps to reproduce

1. Add a section and some entries
2. Add a custom module and remove all core element exporters with the following:

Event::on(
    Element::class,
    Element::EVENT_REGISTER_EXPORTERS,
    static function (RegisterElementExportersEvent $event) {
        $event->exporters = [];
    }
);

Expected behavior

Element action buttons should always be centered in the element index footer.

Actual behavior

Element action buttons are only centered if the "Export..." button is visible; i.e. there is at least 1 element exporter defined for the current element index source.
