py-prompt_toolkit2: updated to 3.0.2

3.0.2:

Fixes:
- Bugfix in the UI invalidation. Fixes an issue when the application runs again
  on another event loop.

3.0.1:

New features:
- Added `new_eventloop_with_inputhook` function.
- Set exception handler from within `Application.run_async`.
- Applied Black code style.

Fixes:
- No longer expect a working event loop in the `History` classes.
  (Fix for special situations when a `ThreadedHistory` is created before the
  event loop has been set up.)
- Accept an empty prompt continuation.
- A few fixes to the `Buffer` tempfile code.
