Windows test runner: show process name instead of test name
Windows test runner: show process name instead of test name

If a test failed we would previously see:

  Output from process `test_foo`: blah
  Output from process `test_foo`: (nothing)

This commit changes it to:

  Output from process `test_foo`: blah
  Output from process `foo_helper`: (nothing)
