This addon introduced an integration conflict when tested in a database that had `mail_tracking_mass_mailing` installed, producing this failure:

    Traceback (most recent call last):
    File "/opt/odoo/auto/addons/auth_signup_verify_email/controllers/main.py", line 44, in passwordless_signup
        sudo_users.reset_password(values.get("login"))
    File "/usr/lib/python2.7/contextlib.py", line 24, in __exit__
        self.gen.next()
    File "/opt/odoo/custom/src/odoo/odoo/sql_db.py", line 419, in savepoint
        self.execute('RELEASE SAVEPOINT "%s"' % name)
    File "/opt/odoo/custom/src/odoo/odoo/sql_db.py", line 154, in wrapper
        return f(self, *args, **kwargs)
    File "/opt/odoo/custom/src/odoo/odoo/sql_db.py", line 231, in execute
        res = self._obj.execute(query, params)
    InternalError: no such savepoint

Which in turn produced the following in the next test:

    InternalError: current transaction is aborted, commands ignored until end of transaction block

The problem comes from the fact that one cannot rollback to a nested savepoint if the parent savepoint was released. It became a problem because that's the strategy that both this addon and upstream's `TestCursor` follow.

To avoid that, tests now mock the `send_mail` method. This results also in having a predictable outcome from the test `test_good_email`, so it is more meaningful now.

Besides, previously we were using the `validate_email` package, which is currently a dead project that can silently fail under certain environments, as seen in syrusakbary/validate_email#80.

There's the `email_validator` package, freely available, supported, and it provides a human-readable error message whenever some format from the email fails.

As such, here I'm switching the dependency, while still adding a backwards compatibility layer for preexisting installations.

* When try to login with a not valid email domain it raised a 500 server
  error. Now we shwt the proper message "The domain name <domain> does not
  exist."
* If there is any error we do not have catched when we do the email
  validation then we manage it and show the error message to the user instead
  of 500 server error.
* When we try to register with a already registered email it raise "Something
  went wrong, please try again later or contact us". Now shows the message
  as odoo regular signup does: "Another user is already registered using this
  email address" which is more specific and clear for this case.

This commit fixes 2 problems:

1.  `auth_signup.allow_uninvited` ICP is no longer used.
    The new equivalent is `auth_signup.invitation_scope=b2c`.
2.  If running tests in an environment where `website` is installed,
    the website needs to get public signup enabled or tests here would
    fail with an error like this:

In one part of the CI pipeline, the IANA example domains are not
accepted, getting this message from `email_validator` library:

The domain name example.com does not accept email

So we switch to a real domain for avoiding the problem, using our
famous main OCA list address, which at the end, it's not secret and
won't be disabled in a short future.
