todoman: test default due fails with assertionerror

Hi,

In the last update in Archlinux (updating from 2.0.2-1 to 2.1.0-1) I got the following failure while performing the test test_default_due2

________________________________________________ test_default_due2 _________________________________________________

tmpdir = local('/tmp/pytest-of-XXXXXX/pytest-9/test_default_due20')
runner = <click.testing.CliRunner object at 0x7f9b9d3f4f60>
create = <function create.<locals>.inner at 0x7f9ba0de31e0>
default_database = <todoman.model.Database object at 0x7f9b9d3f4b00>

    @freeze_time(datetime.datetime.now())
    def test_default_due2(tmpdir, runner, create, default_database):
        cfg = tmpdir.join('config')
        cfg.write('default_due = 24\n', 'a')
    
        r = runner.invoke(cli, ['new', '-ldefault', '-dtomorrow', 'aaa'])
>       assert not r.exception
E       assert not InvalidArgsError(<class 'icu.SimpleDateFormat'>, 'format', (FakeDatetime(2003, 10, 30, 11, 45),))
