Steps I did
Create to new users. for example olof and user2
Delete said users.
Add a new user with higher alphabetical order, for example aaatest.
Add olof and user2.
User /home/olof will now owned by aaatest
Resulting in pubkeys non-accessable pubkeys for example.
Tested on VyOS 1.1.7 with ansible 2.6 and vyos_user module.
It doesn't look like the same thing is happening on 1.1.5.
It looks like the delete user script in 1.1.5 keeps line in /etc/passwd AND /home/$USER dir
while in 1.1.7, the script is only deleting line in /etc/passwd.
