Use node API for trash bin with special flag for getSize()

[MorrisJobke]

• reverts the backported fix from Bugfix for issue 10862: Trash-bin ignores trashbin_retention_obligation #13844
• uses add option to get raw size (without submounts) from fileinfo #14412

Now the node API is properly used again.

This fixes #10862 on master

Looks good to me.

Is it safe to make the same changes (i.e. switch to the node API) in the files_versions app?

server/apps/files_versions/lib/Storage.php

Lines 753 to 755 in fb5a249

	$files_view = newView('/' . $uid . '/files');
	$rootInfo = $files_view->getFileInfo('/', false);
	$free = $quota - $rootInfo['size']; // remaining free space for user

I would say so. 👍
