Title: Fix To $entity->modified() For Nested Data

I found that the text for `$entity->modified()` from pull #423 wasn't testing for sub-documents, arrays, or document arrays. I updated the test and made several modifications to fix the failures I found.

I'm nervous that we're still missing test cases. Fixing modified() to not just assume every field is modified is pretty dangerous because if this goes to master with a bug, then people running on master will have incorrect data in their databases.
