perf: Skip doing a query just to check if a board is deleted

[juliusknorr]

Instead of doing one sql query to fetch the card details for each card that has an incoming file share we can just filter out deleted cards upfront and skip the check for it.

The extra query that is skipped is:

deck/lib/Service/PermissionService.php

Lines 121 to 130 in a35489b

	if (!$allowDeletedCard && $mapper instanceof CardMapper) {
	try {
	$card = $mapper->find((int)$id, false);
	} catch (DoesNotExistException $e) {
	throw new NoPermissionException('Permission denied');
	}
	if ($card->getDeletedAt() > 0) {
	throw new NoPermissionException('Card is deleted');
	}
	}

Steps to reproduce:

• As userA create a deck board
• create 12 cards with file attachments
• share the board to userB with edit permissions
• As userB send a propfind request to the root directory (or setup the file system in any way)
