Expected Behavior

When I run a pipeline with tkn pipeline start <pipeline-name> --showlog and the pipeline fails, I expect the return value of the tkn command is also non 0. In this way it is possible to start a pipeline from another pipeline and fail the first one, if the second one has failed.

Actual Behavior

The return value of tkn pipeline start <pipeline-name> --showlog is 0, if the started pipeline fails.

Steps to Reproduce the Problem

1. tkn pipeline start <pipeline-name> --showlog || echo "run failed"

The "run failed" string is never shown, even if the started pipeline failed.
