can't reset password without email server set up

[ngbusca]

Issue Summary

In order to reset a user's password on a redash instance without an email server set up, the systems suggests the use of a reset link instead. However, the password reset link lands on an error page: "This invitation has already been accepted. Please try resetting your password instead."

Steps to Reproduce

1. start a redash instance without setting up an email server
2. create a user
3. from the admin account go to users>the created user>send a reset email>get a reset link (since email server is not active)
4. follow the reset link
5. get the error message:

The expected behavior should be for the reset link to work.

Technical details:

• Redash Version:7.0.0+b18042 (4a978ba)
• Browser/OS:Chrome/Mac
• How did you install Redash: docker

This is a duplicate of #3675 and was fixed in v8. I recommend upgrading to the new version, but if that's not an option at the moment, you can try one of the workarounds discussed in #3675.
