Fixed bug in quoteInto with $count parameter and question sign in $value

Fixes bug when you use `$count` parameter and your `$value` contains question mark.

For example following code:
```php
    $value = 'What?';
    $where = $adapter->quoteInto("name = ? OR description = ?", $value, null, 2);
```
returns invalid result
```
    name = 'What'What?'' OR description = ?
```
instead of
```
    name = 'What?' OR description = 'What?'
```
