[document_repository] Uploading file too large not reporting correctly

[jeffersoncasimir]

Uploading a file too large returns a 400 response instead of the intended response that reports the error on test-dev-260.

The log error when uploading a 1GB file: POST Content-Length of 1073757430 bytes exceeds the limit of 1073741824 bytes

I believe if the post_max_size was increased, the upload_max_filesize limit would be triggered and it would report correctly.
