If we have the uncertainties library loaded, go ahead and use the uncertainty_tokenizer by default.  This fixes problems with standard Pandas tests that expect the tokenizer to do the right thing without any special setup.

Also, prevent exception when a loop in consensus_name_attr (pandas-dev/pandas/core/common.py(86))) tests equality with a None argument.   Otherwise the zero_or_nan test raises an exception.
