strconv.convert('') returns a datetime of today's date

[armike]

I expected either None or '', but a datetime was completely unanticipated. A converter for None-like inputs might do the trick, or '' could be treated as a string.

It's due to behavior in the from dateutil.parser import parse section.

I think that best place to change it this line https://github.com/bruth/strconv/blob/master/strconv.py#L117

two solutions, either use a different module, like from dateparser import parse as duparse or use something like this, if isinstance(s, str) and s.strip() != '': in line 117

In version 0.4.2 (installed from this repo, not PyPI, see #12):

In [15]: strconv.convert('')
Out[15]: ''

In [16]: strconv.infer('') is None
Out[16]: True
