CI test always succeed because error strategy is ignore and exit code is 0

[gongyixiao]

Current CI test always succeed even when job failed because the workflow's error status is 0.

This happens in commit a9bdff1 when PR #949 was merged.

We either need to change error strategy in conf/test.config file to teminate/finish or add workflow.failOnIgnore = true in it.

But this setting only available in higher version of nextflow

nextflow-io/nextflow#5071

Also due to this line, SomaticRunSVCircos is not running in travis-ci test.
