Add redirect after password reset

[lukavdplas]

When a user uses the "forgot password" option to reset their password, they end up on the password reset form (PasswordResetComponent). After successfully submitting a new password, the user receives a notification but isn't redirected, so it can look like nothing happened. The form will become invalid at this point, so if the user tries to hit "submit" again they get an error that the URL is invalid, which is confusing.

Solution: add a redirect to the home page after the password is set.
