CommandCalls

Sends the synchronous calls of a saga's execution to other contexts: the runtime's HTTP client on a node, an answer of the test DSL in a domain module's test. call returns the target's result as it is, SUCCEEDED, REJECTED or FAILED, and throws a WowProblemException (failure) when it reaches none; ExecutionSagaContext.call turns the results that did not succeed into the handler's typed failures.
