Hello,
My decidim is on production and my system is blocked for some Amendments and private participants.

I am a beginner with rubys on rails and I do not understand certain subtleties. I'm going to make the modifications you made, but I don't have the files (was there a compilation, then deletion of the files?)

My question is:
how to resolve the concerns already present? (user delete or add missing data by hand to the database? but what data to submit?)
and
How to make your modifications on my server, knowing that I don't have the files?

Many thanks for your time!

Closing this PR in favour of 5803.

It turns out that changing the behavior of the registrations controller is not difficult, but then there are other use cases to take into account in when the user accepts the invitation after having registered, tacking these is out of scope for the current bugfix, e.g:

• the admin re-sends an invitation to the already registered user
• an impersonated user is promoting its account
