Make spawn_n() stub properly ignore errors in the child thread work

When we call spawn_n() normally, we fork off a thread that can run or
die on its own, without affecting the parent. In unit tests, we stub
this out to be a synchronous call, but we allow any exceptions that
occur in that work to bubble up to the caller. This is not normal
behavior and thus we should discard any such exceptions in order to
mimic actual behavior of a child thread.
