one-way-number-mask types one or many "0" characters in odd circumstances

[hergaiety]

I've written these two failing tests for one-way-number-mask-test.js.

  test('It does not input a zero when hitting "."', async function(assert) {
    await render(hbs`<OneWayNumberMask />`);
    await fillIn('input', '.');

    assert.dom('input').hasValue('');
  });

  test('It does not input a zero when hitting "m"', async function(assert) { // This also happens with the letter `k`
    await render(hbs`<OneWayNumberMask />`);
    await fillIn('input', 'm');

    assert.dom('input').hasValue('');
  });

Maybe the reason is the "shortcut" option. If you type "m", it's replaced by "000000". I cannot turn it off passing @options={{hash shortcuts=null}} though.
