Fix bug with new list not being populated correctly on creation

- This was preventing the first value a user saved in a list from being set
  properly.
- To reproduce:
    - Run `clip <new_list> <key> <value>`
    - Run `clip <new_list>`
    - Notice that the 'value' of the above specified key would be `Created
      <new_list> list` instead of the value user tried to save.
