Token access section in admin profile is blank

Can you try this?

root> zammad run rails c
rails> t = Token.find(19)
rails> t.preferences = {"permission"=>["ticket.agent"]}
rails> t.save!
rails> t = Token.find(18)
rails> t.preferences = {"permission"=>["cti.agent","ticket.agent"]}
rails> t.save!
rails> t = Token.find(17)
rails> t.preferences = {"permission"=>["cti.agent","ticket.agent"]}
rails> t.save!

This should fix user id 4 hopefully.
