io.html.read_html returning table "twice"
Forgive the markup indentation.

``` python
from pandas.io.html import read_html
read_html('http://www.epexspot.com/en/market-data/auction/auction-table/2005-10-25/DE',
attrs={'class': 'list hours responsive'},
skiprows=1,
parse_dates=False)
```

returns a list of two data frames where the first one is equivalent to `read_html()` without the `parse_dates` arg and the second one is the one expected to be returned by calling `read_html()` with `parse_dates` arg.

Am I missing something?
