* Do not extract nested paths from the object keys contained in middleware hook return values

Fixes #966

* Additional test for #1130

* Nit: trailing space

* Post-merge fixup

* Add explicit check for keys as literal property names on objects before intepreting them as paths

* Alternative approach: push logic down into setByKeyPath function

* Revert "Alternative approach: push logic down into setByKeyPath function"

This reverts commit d610245.
