No file-uploading possible at all

[alexdetsch]

Steps to reproduce

1. Upload a file through the webinterface or the desktop-sync-client
   file size seems to be irrelevant, but it is possible to create and edit a textfile with the webinterface-texteditor until its some 100B big.

Expected behaviour

The file should be uploaded and shown in the webinterface.

Actual behaviour

The desktop-client throws an error, that the server closed/interrupted the connection, the webclient stop after a while and reloads the site.
It seems that this error happend also some time ago with ownCloud, but no of the suggested patches worked for me. This guy has the same issue with Nextcloud 10: https://help.nextcloud.com/t/400-expected-filesize-exception/2835

Cause the error happen in the backend (WebDAV-client is irrelevant), I don´t include it.
