Fix bug where comments were not updated in reply dialog

So this has to do with the way Polymer does dirty checking
from within dom-repeat. Since the underlying array instance
identity was not changed, the dom-repeat would not trigger
and the reply dialog was not updated properly.

Additionally:
+ Guard against searching for a saved draft when discarding
  one that hasn’t been saved.
+ Move _files to be a compute function.
