User registration issues

[iosonosempreio]

When a new user registers:

• When pressing the confirmation button no feedback is returned in the interface. Should return a message telling to wait for activation
• If not activated, the login attempt returns a wrong credentials message. In case the credentials are correct, the interface should report that the account has still to be activated

The functionality was already implemented, the problem occurred if the email settings weren't configured properly so i added an integrity check.

The problem is back, without changing the previously working email settings.
