Make pathExtract more robust - option to give either suffixes or full stream names

Fix pathExtract, used by some tools such as hotSpotInHIST and checkCorrelInHIST, to be a bit more robust when it comes to expanding the stream name. If the prefix is already present in the provided stream, don't do a lookup.
