fix(lib): restore onConfirm and onCancel

- Restores the `onConfirm` and `onCancel` properties given to
  programmatic `Dialog.open` because I came up with a better workaround.
  `Dialog` continues to accept `confirmCallback` and `cancelCallback`
  instead of `onConfirm` and `onCancel` but `Dialog.open` forwards
  `confirmCallback` and `cancelCallback` calls to `propsData.onConfirm`
  and `propsData.onCancel` respectively.
  Restores also the `onCancel` property given to programmatic
  `Modal.open`. `Modal` still needs `cancelCallback` instead of
  `onCancel`.
