Description

Beam 2.19 causes the following error to occur in an IPython notebook:

/usr/local/lib/python3.6/dist-packages/apache_beam/utils/interactive_utils.py in alter_label_if_ipython(transform, pvalueish)
ipython prompt metadata. Cannot figure out the pipeline '
that the given pvalueish %s belongs to. Thus noop.'
 ---> 84 % pvalueish)
if (pipeline

1. We only alter for transforms to be applied to user-defined pipelines}}TypeError: not all arguments converted during string formatting

The fix should be that the formatter should pass "% (pvalueish,)" instead of the possible tuple.
