fix: [BUG] Invitation to join space : notification is never updated -E…

…XO-75048 - Meeds-io/meeds#2531 (#4142)

Prior to this change, if a user is invited to join a space, and he
accepts, the join notification is never updated. This commit fix this
bug by correcting the update notification method since the condition to
check if the notification should be updated or not was wrong.
