File sync breaks when PC goes to sleep during file transfer

[spotlesscoder]

Steps to reproduce

1. Add many large files (mp4 - few hundreds to few GB each) to the folder
2. Let the sync progress
3. Sync interrupts probably because disk IO stall on target server
4. restart sync
5. sync progresses again
6. repeated this like 3 times
7. left pc - pc goes to sleep to save power after 10m
8. woke up pc again by keyboard, logged in
9. last file was stuck at 3,08 / 4,67 GB
10. Clicked "restart sync" for the account - no progress
11. Quit Opencloud Sync Client - sync started again but stopped at 1010,3 MB / 4,67 GB
12. clicked "restart sync" again - progress jumped to 3,08 GB but stuck there again

Expected behavior

File transfer proceeds and finishes successfully

Actual behavior
