Don't show 'Cancel running' button when pipeline has not been processed
Description
Currently when all jobs within a pipeline have status created, which means that pipeline has not been processed yet, we still show Cancel running button, but it makes no sense in that context.
Pipeline can be unprocessed when it has been canceled due to exceeded CI/CD Quotas / Limits, or when there is a significant problem with a Sidekiq processing.
Proposal
Don't show Cancel running button, when pipeline has not been processed yet.
