Protect against failure to show local data....

Protect against failure to show local data. See https://github.com/napari/napari/pull/3201 where formatting traceback was failing and lead to silenced errors. With this change we instead get the rest of the traceback but without the local variables, which is still better.

      Shim to maintain backwards compatibility with old frontend imports.

      We have moved all contents of the old `frontend` subpackage into top-level

      subpackages (`html`, `qt` and `terminal`), and flattened the notebook into

      just `IPython.html`, formerly `IPython.frontend.html.notebook`.

      This will let code that was making `from IPython.frontend...` calls continue

      working, though a warning will be printed.
