Given a tuleap user account jmalko and given two different Google accounts malkovich.john@google.com and john.malkovich@acme-company.com (which is also a google account) and given I had already linked jmalko to john.malkovich@google.com

When I logout from malkovich.john@google.com, and I log into john.malkovich@acme-company.com and I try to log into Tuleap using this account and I link it to jmalko

Then I am logged in but there is a PHP error about a DB unique constraint, but I am redirected soon after.

I should either:

- have an error when trying to link to jmalko, and be unable to link two accounts from the same provider

- OR not have any error and have two accounts from the same provider linked to jmalko
