tests: remove legacy regression test -> double pipe
Description of change
as described at #5373 (closed)
This test was introduced in 07da49b0 and seems to be obsolete since 96e423a6, when child_process was deprecated from c++ land.
Motivation to change this is, that it requires sed and grep on windows, yet being the only occurences of those. I decided to propose deletion, since it's difficult to reproduce the breaking case in the current node implementation.
