SaveAll on new objects does not return objectIds

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest version of Parse Server and the Parse PHP SDK.

Issue Description

When setting liveQuery.classNames in the server config save all doesn't return object Id when saving more than one new objects. I assume that some sort of afterSave trigger is called that strips away the objectId. I've tested this against Parse Server 6. ObjectIds are returned when you saveAll on one object.

Since objectIds aren't returned you can't delete / save etc.

I believe the issue can be found by looking https://github.com/parse-community/parse-server/blob/alpha/src/RestWrite.js#L1607

Steps to reproduce

Actual Outcome

Objects save but objectId is missing

Expected Outcome

Objects save and return Id.

I created a Faliing test for this #503

I can't seem to replicate this on the JS SDK though.
