Description:
------------
When there are 11 total items and you use a LimitIterator to get the 
first 10, CachingIterator::hasNext() returns false even though there
are 
more than 10 items in the initial set.

If there are 12 total items it works as expected.

Reproduce code:
---------------
$items = new ArrayObject(range(1,11));

echo 'there are ' . $items->count() . ' total items' . "\r\n";

$cachingIterator = new CachingIterator($items->getIterator());

$limitIterator = new LimitIterator($cachingIterator, 0, 10);

$i = 0;
foreach ($limitIterator as $item) {
    ++$i;
}

echo 'first page has ' . $i . ' items' . "\r\n";

if ($cachingIterator->hasNext()) {
    echo 'there is a next page';
} else {
    echo 'there is no next page';
}

Expected result:
----------------
The code should output:

there are 11 total items 
first page has 10 items 
there is a next page

Actual result:
--------------
The code outputs:

there are 11 total items 
first page has 10 items 
there is no next page
