Series[datetime64tz] - DatetimeIndex[tz] raises ValueError

[jbrockmendel]

Opening an issue mostly so the upcoming PR can reference it. This is in fact already fixed in master (at least as of 9303315), so the PR is just a test.

Setup:

dti = pd.date_range('1999-09-30', periods=10, tz='US/Pacific')
ser = pd.Series(dti)

0.22.0:

>>> ser - dti
