Disable prefetching on ContentSuggestions

Prefetching allows the collection view to get cells configured by the
item before it is visible. The item will not reconfigure the cell for
this display.
If the CollectionViewController tries to reconfigure the items
associated with this cell in the moment between the prefetching and
the time the cell is visible, the reconfigure will do nothing.

In ContentSuggestions this problem was encounter for the display of
the articles' images.

Revert "Disable prefetching on ContentSuggestions"

This reverts commit 785f2e5f17b252a5c6787dcdc32171095b0b9d5f.

Reason for revert: prefetchingEnabled is iOS 10+ so this is breaking
tests on iOS 9 devices.
