Investigate differing stack traces

[briancavalier]

As reported here, stack traces reported by wire/debug may differ from those provided to the rejected promise returned by wire() or context.wire(). The only way this could happen, afaik, is if a different Error object is being passed to plugin context listeners than is being used to reject the overall wiring promise.

Another possibility is that because wire/debug reports errors from within plugin infrastructure, and thus is being executed within promise nextTurn machinery, the stack somehow looks different, but isn't really ... or the way we're logging it makes it appear to be different.
