Fix: List view renders an empty menu when no actions are eligible.

[jorgefilipecosta]

If no actions are eligible on the list view we render an empty menu. We are checking for actions?.length while we should check for eligibleActions?.length. This PR fixes the issue.

Testing Instructions

I pasted the following code snippet:

function remove_edit_delete_post_capability( $caps, $cap, $user_id, $args ) {
    if ( 'edit_post' === $cap || 'delete_post' === $cap) {
        // Get the current user object
        $current_user = wp_get_current_user();
        // Check if the current user is the user we want to remove the capability from
        if ( $current_user->ID == $user_id ) {
            // Remove the 'delete_post' capability
            // It's done by returning a capability that the user does not have, for example 'do_not_allow'
            $caps[] = 'do_not_allow';
        }
    }

    return $caps;
}
add_filter( 'map_meta_cap', 'remove_edit_delete_post_capability', 10, 4 );

I went to the trash pages section wp-admin/site-editor.php?postType=page&layout=list&activeView=trash
I verified the actions menu is not available. On trunk it is and renders an empty menu:
