Bugfix: reset password does not validate email (#315)

## Changes

- Bugfix the reset password to not validate the email. `clean_email` is
the function that needed to be modified here since it is being used by
the account registration and password reset forms. This function should
allow both cases, that's why I'm adding a condition for when it is a
password reset, it doesn't need to validate the email.
