Remove Site Explorations mock data

The mock data contains no favicon URLs and mislead several testers to
believe that the icons wouldn't work.

As there is already real data available (by setting country to IN and
version to 6 in chrome://ntp-tiles-internal), we should just drop the
test data.

Alternatively, we could also add favicon urls.
