count_all_results() ignores DISTINCT or list of fields

[Huji]

In the following example:

$this->db->select('name, age');
$this->db->distinct();
$this->db->from('people');
echo $this->db->count_all_results();

The query generate looks like:

SELECT COUNT(*) FROM ...

It is expected to look like:

SELECT COUNT(DISTINCT `name`, `age`) FROM ...

The returned number is therefore incorrect.
