Fix bug with PipelineIndentationStyle.None where break instead of continue statement was used (#1497)

* Fix bug with PipelineIndentationStyle.None where break instead of continue statement was used. TODO: Fix test that starts to fail because of this now

* fix last failing test to make None not touch existing indendation

* empty commit since Azure Pipelines did not trigger

* empty commit since Azure Pipelines did not trigger

* Apply suggestions from code review
