Fix farm locking Windows

[nazar-pc]

This PR reverts #2668, adds workaround to support recovery of corrupted farms and adds an alternative to #2668 by locking farm while writing.

The root issue here is Windows again. If file is locked, writes to the file fail with following error:

called `Result::unwrap()` on an `Err` value: Os { code: 33, kind: Uncategorized, message: "The process cannot access the file because another process has locked a portion of the file." }

However, file is still being modified, erased to be specific 🤦

I'm not in the mood right now, but I'll try to create a bug report to Microsoft about this as well.
