Add better error message when command failed and remove flaky check

[johscheuer]

Description

Return the actual command that failed. Also remove the Eventually statement as that one was flaky, there was a race condition where the test detected the process and then the operator updated that Pod with the new version, which would cause the test to fail (as the process would be missing and MustPassRepeatedly(5) was set).
