Transaction Controller in "Generate Parent Sample" mode : Assertion fails while is should not

**shmulikk** ([Bug 54481](https://bz.apache.org/bugzilla//show_bug.cgi?id=54481&redirect=false)):
I have a response assertion on the root of my test plan.
I have setup a transaction controller and inside it an http sampler.
The assertion works just fine for the http sampler, but it also asserting the transaction controller and failing it with a "Response was null" error.

This now forcing me to duplicate the assertion as a child of each relevant http sampler instead of having just one, at the root of the test plan.

I don't see any reason for assertions to assert logic controller.
