Adding a contact when group is selected creates new groups

[Luto73]

When a contact group is selected and you add a contact the new contact gets the group name set to serveral the single letters the group name consists of. For example: if you select the group "Coworkers" and add a new contact this contact will be placed in the groups "C", "o", "w", ".", "r", "k", "e", ".", "s". (see screenshot)

Steps to reproduce

1. select a group within the contacts app
2. add a new contact

Expected behaviour

The member group should not be split up in single letters. Instead the new contact should be member of the selected group.

Actual behaviour

Instead the group name is split up into single letters and these "groups" are assigned to the new contact.

@skjnldsv how did we miss this? 🤦‍♂️

Can confirm, I have this too. Would be nice to see a fix, although it's not something I would put a high priority on
