Description:
------------
When setting the result of sqlite_query to a result set, if there is an error, error_msg is not set.  Example:

$result = $db->query("asdfesdfa", SQLITE_NUM, $db_error);

i would like to note, however, that if i dont set the results into a result set, it works just fine.  Example:

$db->query("asdfesdfa", SQLITE_NUM, $db_error);

Reproduce code:
---------------
$db = new SQLiteDatabase("sqlite_db1");
$result = $db->query("asdfesdfa", SQLITE_NUM, $db_error);
print">> $db_error<br>\n";
$db->query("asdfesdfa", SQLITE_NUM, $db_error);
print">> $db_error<br>\n";

Expected result:
----------------
>> near "asdfesdfa": syntax error
>> near "asdfesdfa": syntax error

Actual result:
--------------
>>
>> near "asdfesdfa": syntax error
