Length of stream does not match given range

Facts:

1. The following code fails with

Neptune server returned status 400.
{"code":400,"title":"Length of stream does not match given range","errorType":"BAD_REQUEST"}

1. if I set n_jobs=1 it doesn’t fail anymore
2. if I decrease the path length in HERE it doesn’t fail anymore even with n_jobs>1

We tracked down what was happening, we created https://github.com/neptune-ai/neptune-client/pull/573 that should fix it.

Resumes tried to upload the sourcefiles again by default - we’re changing this to make resume not upload any sources by default.

Once this fix is released we’ll update docs to reflect this

Should not occur anymore in 0.9.15.
