Parse-Swift: ParseInstallation does not store object ID in key-value store

Assume a struct MyParseInstallation conforming to ParseInstallation.

If I understand the code correctly, calling MyParseInstallation.current?.save { (result: Result<AppInstallInfo, ParseError>) in [...] } intends to persist the ParseInstallation data to the server.

However, calling MyParseInstallation.current?.fetch(completion: { (result: Result<AppInstallInfo, ParseError>) in [...]} always returns a failure.

Problem seems to be that objectId of MyParseInstallation is not persisted to the ParseKeyValueStore. Thus, the fetch returns ParseError(code: ParseSwift.ParseError.Code.unknownError, message: "Cannot fetch an object without id")

Another effect of not storing objectId in the key-value store is that multiple calls to MyParseInstallation.current?.save result in multiple ParseInstallation objects being created on the server, all with the same data but different ids.

Tested on both the latest release and the removeDispatch branch.
