dsoares 8e7e22c656 Avoid PHP fatal error ...

After last change to file `rcube_ldap.php`, my roundcube instance was getting this error:
```
PHP Fatal error:  Cannot use object of type Net_LDAP3_Result as array in ...
```
In
```php
protected function extended_search($count = false)
```
`$result = $this->ldap->search()` returns a LDAP object (whatever package we use).
If the search returns no results (and if `$is_extended_search` is false), then it gets to line 971 trying to do a `usort()` and then a `count()` on an object, instead of an array.
