I can't setup git-tree hashes right

It matches size, modes and filenames, but not the hash

I pass String content of nested objects to Sha1

I had same problem with different hashes. My bug was that I didn’t include blob header blob <size>\0<content> and just created hash from alone. Maybe you have same problem

@Babihac @gregor-tokarev just checking, do you still need assistance with this?
