test: redirect stdout/stderr of TEST-04-JOURNAL to console as well

This effectively reverts fa6f37c just for TEST-04, as we nuke the
journal repeatedly in this test which makes it particularly hard to
debug. Let's hope the issue behind fa6f37c won't bite us back in this
case.

Follow-up for: fa6f37c
Reverts: 8f7c876

(cherry picked from commit b3ed080)
