Huge BC break for fetchAssoc and fetchPairs

[SendiMyrkr]

• bug report? yes
• feature request? no
• version: 4.0.0-RC2

Description

At least fetchAssoc and fetchPairs ignores setResult, following example works for dibi 3, dibi 4 throws "Unknown column 'playerId' in associative descriptor"

Steps To Reproduce

$q = dibi::select('player_id')->from('players');

$q->setupResult('setRowFactory', function(array $row) {
    $line = new \stdClass();
    $line->playerId = $row['player_id'];

    return $line;
});

print_r($q->fetchAssoc('playerId'));
print_r($q->fetchPairs('playerId', 'playerId'));

Yes, there is actually a BC break here. I did not expect anyone to use RowFactory in this way.
