Description
This ticket fixed a bug in SERVER-42390 that didn't allow upserted documents to have missing shard key fields. The behavior is the same as should have been communicated through SERVER-42390's downstream changes, I only gave this ticket downstream changes to make sure it's clear the bug wasn't the intentional behavior.
Description of Linked Ticket
SERVER-42390 allowed users to insert documents that are missing shard key fields and unset shard key fields through an update. An upsert that doesn't match an existing document takes a different code path than other updates, which currently incorrectly will reject a write that would result in a document without a shard key field because of this check. Instead, the upsert path should only assert the shard key paths do not contain arrays and that _id is present and does not contain an array.
