Remove service annotation for ImperativeBluePrintWorkflowService

Even with the PROTOTYPE_SCOPE annotation the bean was in effect
a Singleton, as it was only injected in one other service. The
class has field variables which would be shared by every thread,
potentially causing severe errors under parallel execution.

Removed annotations to disable dependency injection, and instead
create a new instance with every execution call.
