Async Propagation shows 4bytes on empty space

[kobergj]

          I discovered a bug: After running https://github.com/owncloud/cs3api-validator/pull/18 on my local ocis with async propagation, my space is empty but shows 4 bytes used.

I suspect we have an issue with deletion.

@butonic @aduffeck what happens if you delete a file A/B/C/testfile.txt and delete B before the propagation has been successful?

Can not reproduce, need more info.

I also failed to reproduce it with manual testing, but the cs3-validator testsuite sometimes (only every 10th run or so) triggers it. I'm still trying to trace it down, but I noticed this error in the logs around the time the problem was triggered, which sounds related:
