"no such file or directory" Doesn't Show Errant File/Directory Path

See original GitHub issue

I just got the following error from memory-fs:

Error: no such file or directory

As you can see, there’s no mention of the path it was trying to use to find a file/directory. However, when I looked at the code it was clear that it intended to share that path:

if(!isDir(current[path[i]])) 
    throw new MemoryFileSystemError(errors.code.ENOENT, _path); // Note the ",  _path"

and indeed, if I added a console .log …

if(!isDir(current[path[i]])) console.log(_path)

it logged the path successfully. So evidently there’s something wrong with MemoryFileSystemError which is causing it to ignore or discard it’s second argument.
