I think we'll need to do a bit more investigation on this as 
FileSystem::getFileStores shouldn't have duplicates (and I think the 
test was checking for that). So I think we need to dig into how we are 
ending up with duplicates in the mount table and then decide if they 
need to be filtered or not.
