Bug description

The "Recently contacted" feature adds duplicates there even if a user with that email address is already in contacts. This could possibly be if an instance uses a shared address book and yourself is not owner of that address book?

The "Recently contacted" mechanism needs to check if an address already exists in Contacts, in which case they should not create another entry, also in other address books you have (at least those which are enabled).

@ChristophWurst as mentioned

Steps to reproduce

1. Send a mail to an email of a person you already have in contacts
2. Check in contacts, they will be twice in the "All contacts" list

Expected behavior

No duplicates should be created. :)
