Fix delete action visibility for OpenDJ/389DS when hasSubordinates/numSubordinates are false/0

[maksonlee]

Summary

On OpenDJ/389DS directories the Delete action for leaf entries is hidden even when the authenticated user has permission to delete the entry and hasSubordinates/numSubordinates indicate there are no children.

This happens in HomeController::frame() when computing page_actions['delete'].

Root cause

page_actions['delete'] currently does:

'delete'=>is_null($xx=($o->getObject('hassubordinates') ?: $o->getObject('numSubordinates'))?->value)
        || (collect($xx)->filter(fn($item)=>$item !== 'FALSE')->count() === 0),

Thanks for creating this. I actually think I've sold the issue a better way with 1915410 - but let me know if this continues to be a problem.
