Identities of anonymous voters can be discovered by inviting them

[femtobit]

Steps to reproduce:

1. Create a dudel and vote on it anonymously as user1.
2. Log in as user2 and invite user1.
3. You will see the notification "1 users were skipped, since they either are already invited or have already voted." Additionally, in the list of invitees, user1 will be listed as having already voted.

This makes it possible to identify anonymous votes, at least while there is only a single anonymous vote present.
