Code review comment for lp:~gosteven/gtg/fix-816356

Thanks for a patch. However, your solution doesn't work for this scenario:

a (due next week)
b (due next month)
 - c (due tomorrow)

After applying your patch I would expect to have [when sorting by due date, close dates first]

b (due next month)
 -c (due tomorrow)
a (due next week)

(b's due date should be replaced by c's tomorrow)
