Fix edge case when PipelineIndentationStyle is not set to NoIndentation (#1261)

* Fix indentation problem when PipelineIndentationStyle is set to IncreaseIndentationForFirstPipeline or IncreaseIndentationAfterEveryPipeline
The determination if the pipelineAst is on one line needs to be tweaked to include the case where pipelines are on the same line but a multi-line expressions follows

* restart ci

* Apply variables naming suggestion
