gnome-software asks for Ubuntu One SSO authentication when installing snap packages

[Cryptie]

What I expected to happen:
Finding the "Nextcloud"" application, clicking on "install" would install directly the application without any authentication step.

What actually happened:
a windows prompted asking for Ubuntu One SSO authentication.

Minimal series of steps necessary to make it happen:
- start gnome-software
- search for Nextcloud
- click install

If it can helps:
This happened in my classical Ubuntu 16.04 LTS and has been reproduced on a 16.10.
Does not work on my Ubuntu Gnome 16.04.
