Description:
------------
When retrieving a result using fetchRow in FETCHMODE_ASSOC, the returned
array types are incorrect if the query contained several columns with
the same name.

This is caused by the fact that when setResultTypes is called, the types
array contains numeric keys. So for example if you obtain an integer,
another integer with the same name and a textfield, you have three
items. The associative array will contain two entries (one of the
identical fields and one textfield), which are mapped to the entries
with the corresponding index, after converting string keys to numbers.

This happens mostly when doing SELECT * on joined tables, but even
though it's bad practice to select *, mdb2 shouldn't fail this hard on
such things.

The attached patch fixes the problem for me.

Test script:
---------------
// Assuming $connection is a previously set up MDB2 connection
$res = $connection->query("SELECT 1 as id, 2 as id, 'foo' as title",
true);
$record = $res->fetchRow(MDB2_FETCHMODE_ASSOC);
var_dump($record); // Prints 'id' => int 2, 'title' => int 0

Expected result:
----------------
I expect 'id' => int 2, 'title' => string 'foo' to be printed.

Actual result:
--------------
'id' => int 2, 'title' => int 0
