a baseline generated on windows contains backslashes in the "path" property

parameters:
	ignoreErrors:
		-
			message: "#^Declaration of PDF_Angebot\\:\\:body\\(\\$angebot\\) should be compatible with ActionPdf\\:\\:body\\(\\)$#"
			count: 1
			path: app\admin\models\PDF_Angebot.php

using this paths in a linux based CI system renders the ignore rules useless as the paths do not match.

it seems the DIRECTORY_SEPARATOR within those paths should be normalized
