Execution contexts weren't getting set on subscriptions. Seems this has always been the case, and I guess subscribers weren't relying on having an execution context, but they should be able to, so policies don't always have to use their own (although they probably should for anything long-running, for cleaner task separation). This adds a test that shows the problem, then the solution which specially sets the execution context. (Pretty much everywhere else this isn't a problem because we submit via EC rather than ExecutionManager; but in subscriptions we can't do that given how task tags are passed in. Ideally should refactor LSM so that it takes the EC not the tags -- but this is easier and works just as well.)
