Invalid regex pattern for password reset token in 4.2b1

[Dmitriy Sintsov]

Probably the second part of token (32 chars) is too long for {1,20} regex:

NoReverseMatch at /password-reset/

Thanks for this report, however I don't see such regex anywhere in Django. This seems to be an issue in your code.
