recover breaks when custom properties appear as nodes

Hello!

One of our customers has experienced a massive data crash due to a blackout. While restoring (restore 2 5), the following error appears:

INFO:root:Restoring #1106279:OECustomProperty Root/Restore_Test/RESTORED-alt/2012_Jan/Docs_CT.eml:OECustomProperty
ERROR:root:IOError when trying to create /mnt/transfer/Partition2/Root/Restore_Test/RESTORED-alt/2012_Jan/Docs_CT.eml:OECustomProperty

  File "/root/RecuperaBit/recuperabit/logic.py", line 262, in recursive_restore
    os.utime(restore_path, (atime, mtime))
FileNotFoundError: [Errno 2] No such file or directory

Those are custom props. Can I skip them, somehow?
This is from a HyperV VHDX mounted on a Debian VM.

Thanks!

I have yet to get into the shell (it is still assigning and linking entries) but this could help.

Some files don't have any contents BUT attributes, so writing attributes to a file that doesn't exist, won't work. So, this monkey-patch works around that.

Long term, it should be considered if those empty files are to be touched too, causing them to have empty contents instead (if not file_exists(): touch()). However, this could end up causing an absolute ton of empty files, so this should probably be a switch instead for the user to decide (i.e. --touch-ghost-files).
