INVITES: If join via a join link when have also been invited by email, invite still shows as 'pending'

[BeccaMelhuish]

What is the problem?
I invited Meelika by email and also shared a share link in our groupchat. She presumably joined via the join link, so her email invite still shows as pending.

Why is this a problem?
Misleading, should cause confusion.

Possible solution.
The system should recognise when an email in 'Participants' matches one in 'Invited', and if so, remove it from the 'Invited' list (but without retracting the invitation, just not showing it in the list).
