Received shares do not work for viewers

[mateusz-garlacz]

Hi, I am unable to update a received share. The share is not visible on the recipient's site neither. This happens only when the grantee's permissions are set to viewer. Steps to reproduce the issue:

magc@magc:~/reva$ ./cmd/reva/reva --insecure login basic
username: einstein
password: OK
magc@magc:~/reva$ ./cmd/reva/reva --insecure upload test.txt /home/test-viewer.txt
Local file size: 13 bytes

This is not the case when the rol flag is set to editor. I built reva on master commit 393f831 and followed the official README and run it on storage-references config.
