COMPAT: broken pickle compat from 0.19.2 -> 0.20.2 for UTC tz's

[jreback]

In [1]: pd.__version__
Out[1]: '0.19.2'

In [3]: df = pd.DataFrame({'A': [1, 2, 3]}, index=pd.date_range('20130101', periods=3, tz='UTC'))

In [4]: df.to_pickle('v0.19.2.pkl')

broken in 0.20.1/2

In [2]: pd.read_pickle('../v0.19.2.pkl')
IndexError: tuple index out of range

works fine for tz-aware but non-UTC (e.g. US/Eastern is fine).

@jorisvandenbossche @TomAugspurger any objection to doing a 0.20.3 in a few weeks?

[jorisvandenbossche]

No objection. I would just start tagging stuff as 0.20.3 and make a 0.20.3 whatsnew file. If we in the end decide that we don't find it worth to release (which probably will not be the case), we can easily move those things to 0.21 (it's just moving the whatsnew entries).

[TomAugspurger]

Fine by me as well.
