Can't use PATCH for Business Information

Hi there,
I've gotten pretty much everything working nicely except for any function requiring HTTP: PATCH.
For example, updating Location data for a Google Business Profile.
Here's my code:

```
$locationData = (object) [
'title' => "MY_NEW_LOCATION_PROFILE_TITLE"
];
$locationData = json_encode($locationData);

$locationName = 'locations/###################'; // Checked and confirmed using get()!
$params['updateMask'] = 'title'; // Field updated
$serviceBusiness = new Google_Service_MyBusinessBusinessInformation($client);
$updateLocation = $serviceBusiness->locations->patch($locationName, $locationData, $params);
vard_dump($updateLocation);
```

The $client is good because I can run locations->get() and accounts_locations->listAccountsLocations() and even categories->listCategories() without issue. I confirmed the $locationName using locations->get().

But for some reason locations->patch() always dies. I believe it is because of the PATCH http type (as opposed to GET or POST).

Any ideas??

Cheers,
Richard :)
