FUSE error: 'Node' object has no attribute 'remote_path'

[janten]

The patch works, at least no duplicate entries occured to me now. File operations can be done sucessfully both under GUI and CLI. But there're still errors prompting. It says something like

ERROR:fuse:Uncaught exception from FUSE operation flush, returning errno.EINVAL.
Traceback (most recent call last):
  File "/usr/lib/python3.8/site-packages/fuse.py", line 734, in _wrapper
    return func(*args, **kwargs) or 0
  File "/usr/lib/python3.8/site-packages/fuse.py", line 884, in flush
    return self.operations('flush', self._decode_optional_path(path), fh)
  File "/usr/lib/python3.8/site-packages/fuse.py", line 1251, in __call__
    ret = getattr(self, op)(path, *args)
  File "/usr/lib/python3.8/site-packages/dptrp1/cli/dptmount.py", line 289, in flush
    remote_path = os.path.join(parent.remote_path, fname)
AttributeError: 'Node' object has no attribute 'remote_path'

The program continued like nothing happened, and I have no idea on what really went wrong.
