Unconditionally prints to stdout on exceptions

[danvk]

If you try to parse an expression that python-edtf doesn't like, it prints to stdout before throwing an exception. If this is an expected failure and you catch the exception, you're stuck with a noisy console.

>>> import edtf
>>> edtf.parse_edtf("[2011-05-01..2018-06-24]")
trying to Consecutives.__init__(**{'year': '2018', 'month': '06', 'day': '24', 'lower': ['2011', '-', '05', '-', '01'], 'upper': ['2018', '-', '06', '-', '24']})
...

The print statement here should be removed:
