Environment Setup

Ran https://github.com/ParsePlatform/parse-server-example with changes for email adapter on AWS Elastic Beanstalk.

Steps to reproduce

1. Request for password reset for any existing user with username that contains "+".
2. In the password reset email, when the user click the link, "+" gets translated into space.

https://github.com/ParsePlatform/parse-server/blob/master/views/choose_password#L163

Seems choose_password is changing '+' in usernames to ' '. If I change ' ' back to '+' using the browser's dom inspector, changing password works.
