[7.0] auth_signup: global name 'mako_template_env' is not defined

[Aristóbulo Meneses]

Hello, i think i've found a bug.

1. Install auth_signup module
2. Add an Outgoing Mail Server (Settings >> General Settings >> Outgoing Mail Server
3. Configure the outgoing mail server with Gmail recommended settings (https://support.google.com/mail/troubleshooter/1668960#ts=1665018,1665144)
4. Test the server, everything is Ok, then save.
5. Log out, and create a new user account.
6. Check that User is properly created and has an email address.
7. Log out again.
8. Try to recover user password.

Error:
