[TW-1849] UUID displayed instead of ID with custom data.location

I say:

{code}
[killy(at)GLaDOS : ~] t add "Foo"
Created task 21.
[killy(at)GLaDOS : ~] t 21 done
Completed task fd6146d9 'Foo'.
Completed 1 task.
{code}
Notice that the message displayed when a task is completed does not report task ID, but instead uses its UUID. I have tried commenting out various sections of my configuration file and concluded that the single line responsible for this behaviour is my custom setting of `data.location`.
