Wrong Office Open XML detection in ZipContainerDetector

Method detectOfficeOpenXML() in ZipContainerDetector class does not detect correctly an ooxml file due to an Exception throwed by OPCPackage.open(..) POI's class. This class make use of ZipFile when its method is called with (as Tika do) filePath string and in this way it generates an exception; passing instead a fileInputStream makes POI correctly detects OfficeOpenXML formats.
