Issue Description

Cannot update saved ParseObject's using saveAll due to the SDK encoding the batched objects as Parse pointers.

Related issue: #405

Approach

Detect when batching and don't convert the ParseObject being saved to a Parse pointer.

TODOs before merging

• Add tests
• Add entry to changelog
• Add changes to documentation (guides, repository pages, in-code descriptions)
