Fix some issues with new Conduit method implementations

Summary: Ref T5655. A few of these were missed.

Test Plan:
Checked all other methods like this:

```
    foreach ($method_map as $k => $v) {
      $v = preg_replace('/ConduitAPIMethod$/', '', $v);
      $k = str_replace('.', '', $k);
      $v = strtolower($v);
      if ($k != $v) {
        echo "{$k} x {$v}!\n";
      }
    }
    echo "OK\n";
```
