User invite email fails if visited more than once without completing

#17681

This PR looks to reset the security stamp back to previous when doing the signin behind the scenes in the same way lastlogindate is being reset. This allows the action to happen again until the user completes the process.

Hi @dchallener ,

Thanks for your PR to implement #17681, and stop the user invite email failing if it is visited > once without completing.

One of the Core Collaborators team will review this as soon as possible - it also seems like one that we want HQ to review, so I'll contact them about it.

Best wishes

Emma

Thanks @emmagarland ,

Let me know if there is anything else required in the meantime. Would be super great to get this into an upcoming release as is causing us issues with clients using mail scanners or link checkers.

Best wishes,
David

@dchallener thanks David, we're currently in discussion with HQ about this as it might be some surrounding code needs tweaking. I'll let you know as soon as we have a decision on the best approach!
