lib.App: Reformat imports with trailing commas

Running make format with the new isort setting rewrites the two wrapped
import blocks:

- The argparse import is split one-per-line, since the logical line exceeds
  88 columns
- A trailing comma is added to both imports, which makes yapf keep the
  split layout instead of re-joining it

The result is a fixed point that both isort and yapf accept, so make format
and make check agree.
