[FIX] website: multi website - auto public user

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'
