Passing [ci skip] now creates a pipeline and shows the pipeline as skipped via the UI

Our organization passes [ci skip] for pipelines.

When we first started utilizing this (11.6), gitlab CE did not show these pipelines in the UI. This is desirable as we are passing [ci skip] so we clearly don't want to create a pipeline.

Now (11.9), these pipelines are created even when [ci skip] is passed. This creates noise in the UI.
