fix(core): Remove circular dependency in WorkflowService and ActiveWorkflowRunner (#8128)

## Summary
A circular dependency between `WorkflowService` and
`ActiveWorkflowRunner` is sometimes causing `this.activeWorkflowRunner`
to be `undefined` in `WorkflowService`.
Breaking this circular dependency should hopefully fix this issue.
