Fix #12414
Summary
If you load a document with an array deselected
const doc = await Model.findOne().select({ arr: 0 })and then save with no changes, Mongoose will save an empty array. This looks like it applies to all deselected defaults.This PR makes it so that Mongoose skips deselected defaults when calculating what changed in the document.
