properly handle null data when denormalizing

If null is passed to denormalize(), no property values can be set on
the denormalized object. Additionally, this fixes passing values to
the denormalized object's constructor if the incoming data is an object.

This pull request fixes the issue described in #11421.  It also adds a test for the issue.  The issue is present in 2.0 forward, but I decided to fix it on the 2.3 branch so that I could also write a test for it (2.0 had no tests for the Process component, and 2.1 and 2.2 didn't have tests for the `ExecutableFinder` class).
