Before this commit
When user was in company A and try to create a second website for company B an
error was raised, because the search from user in company A don't find a public
user in company B and the same default user (public-user@company-B.com) was
created again before to be catched and raised by the sql contraint login_key.
Now we use '-' instead of '_' to avoid parser of email to detect it as invalid
After this commit, we don't have anymore the error:
- 'You can not have two users with the same login!'
or - 'Login must be a valid email address'
