Subject: [PATCH] fs: fix Don't know how to set key "chunkSize" on upload
 errors in tests

Before this testing any backend which implemented the OpenChunkWriter
gave this error:

    ERROR : writer-at-subdir/writer-at-file: Don't know how to set key "chunkSize" on upload

This was due to the ChunkOption incorrectly rendering into HTTP
headers which weren't understood by the backend.
