test(ivy): add root cause analysis for the remaining projection test (#28152) 

Initial thinking was that the bug is in the content projection logic but
it turned out to be a wrong assumption - hence adding a test to illustrate
that basic content projection of view containers works correctly.

What fails in the marked test is the logic quering debug nodes - content
peojection is fine but we never create the 'B' text node since we call
show() method on the "wrong" directive instance.
