kernel: Different thisContext setup.

Context tree is hydrated in accordance
with TMethodContext handling of the context;
specifically, chain goes to outerContext if present,
only otherwise to homeContext.

Cleaner solution would be to hydrate the chain
in Smalltalk code and free kernel of these decisions.
Maybe later.

+===================================

+* Changed thisContext hydrating in kernel
+  * Set up so better stack traces are shown in debugger, esp. for async
+  * Can be breaking for code that depends on old hydration (unlikely).
