When an iterator has been used in a template just as `{$iterator}` and not
as `{$iterator->counter}` (as documented), it has thrown a kind of confusing
error:
Fatal error: Method Latte\Runtime\CachingIterator::__toString() must not
throw an exception, caught BadMethodCallException: Latte\Runtime\CachingIterator
does not fetch string value (see CachingIterator::__construct) in *PATH* on line 0
This patch allows conversion to a string by returning the current counter.
