test: delete parallel/test-process-active-wraps

It is supposed to test an internal debug feature but what it effectively
ends up testing, is the exact lifecyle of different kinds of internal
handles.

Lifecycles are different across releases and platforms, making the test
fail intermittently or, in some environments, consistently.  It's not a
good test, delete it.
