mod_component: Distinguish missing stream @to from unknown local component (thanks Daniel_W) Spectrum2 did not include a stream @to attribute due to a configuration error. "nil does not match ..." is not very clear in pointing this out and is somewhat confusing, tho it did help pinpoint what went wrong. It's also not great leak to programming language internals like "nil" out into user-facing strings like this.
