function members() bug

[itouchdennis]

Returns no member, if there is just one member in the given group.

Hint: if there is only 1 member there, the $group['member'] is not an array.
One possible fix:

`
public function members($group, $fields = [])
{
$group = $this->find($group);

    if (is_array($group) && array_key_exists('member', $group)) {
        $members = [];

        if(!is_array($group['member'])) {
            $group['member'] = [$group['member']];
        }

        foreach ($group['member'] as $member) {
            $members[] = $this->adldap->search()
                ->setDn($member)
                ->select($fields)
                ->where('objectClass', '=', 'user')
                ->where('objectClass', '=', 'person')
                ->first();
        }

        return $members;
    }

    return false;
}
