Fix nested --github-output group for progress report nested inside timeline

Do not emit group when progress report is nested in timeline or failure.
Unfortunately github logging does not handle nested groups correctly.

Commit 606c1cb passed "isVeryVerbose" as
to argument "emitGroup", while should pass to "emitGinkgoWriterOutput".
So, it break fix added in commit fdc65b1.
