Need 'access deleted contacts' permission to retrieve loc block addresses using API

If you want to retrieve an address using the API like this:
$result = civicrm_api3('Address', 'get', ['id' => $myAddressId]);

And if this address is a loc block address (e.g. the location of an event), no address will be retrieved, because 'contact_id' of a loc block address is NULL.

I have a hacky patch to work around this; I will post it in a minute.
