Subject: [PATCH] Fix judgehost check if its enabled

array_filter would only filter out the other judgehosts but still return an array of judgehost objects. By selecting the first (and only item) we can now get the `enabled` property and properly check.

```
array(1) {
  [1]=>
  array(5) {
    ["id"]=>
    string(1) "2"
    ["hostname"]=>
    string(8) "judgehost"
    ["enabled"]=>
    bool(true)
    ["polltime"]=>
    string(20) "1728821560.017400000"
    ["hidden"]=>
    bool(false)
  }
}
```
