Cannot import InteractiveRunner as IPython.display is no longer a valid symbol.

This was when attempting to use apache_beam's interactive runner in a local ipython interpreter.

Cannot import InteractiveRunner as IPython.display is no longer a valid symbol.
Added AttributeError to catch this case.

Changing line 45 in apache_beam/runners/interactive/display/display_manager.py seems to fix it:
except (ImportError, NameError, AttributeError):

The code path that breaks is when using ipython from a command line. (not a notebook)

To reproduce you can start an interpreter and import the interactive runner:

/google/data/ro/projects/g3python/g3python --deps //third_party/py/apache_beam
from apache_beam.runners.interactive import interactive_runner

The error:
