fix(circleci): CircleCI Workflow nil check for CreatedDate (#8310)

* fix(circleci): Add CircleCI workflow nil check for CreatedDate

Adds a nil check during `convertWorkflows` task when CircleCI workflows API returns a weird malformed pipeline data with no created_date. Previously, the entire task fails and panics when trying to get convert a nil in ToTime util.

Fixes Issue #8309

* Update to fix compile problems

* Tweak the _tool csv to allow for the NULL value entries
