Display of poll results will break if everybody spoilt their votes

[Guilherme Salgado]

The IPoll.getWinner() method will break if the option with the most number of votes is NULL (None of the above). We need to fix it and make sure we display the number of people who voted for "None of the above".

OOPS-102C183 shows the issue.

OOPS-935H371 TypeError: int() argument must be a string or a number

Recent OOPSes: OOPS-1000A3798, OOPS-1000F1293, OOPS-1000F2009

this is actually very unlikely to happen in practice, so I'm reducing its importance

The fix on my branch will get rid of the OOPS and report that these polls have no winners.
