Fix spawn kill mix-up.

[hjoliver]

The (infrequently used!) spawn command was killing target tasks ... looks like a cut-n-paste error in the new network layer.

As this is a bug, and easily fixed, we'd better put it in next release. Clearly we need cylc spawn tests with this - but I won't have time tonight.

Sorry I had actually spotted this while doing#2373, but had forgotten to raise a separate fix.

[matthewrmshin]

Perhaps we should have a better test for the command?

[matthewrmshin]

Can't argue with the change otherwise.

(In this case, test should not be a blocker for the release.)

Yes we should - a quick grep suggests we don't have any for it.

@oliver-sanders has just raised a new bug (2411) and labeled it for next release as well - and it is sufficiently bad (log duplication) that I think we should wait on that first anyway ...

Yeah, I'll merge this - it's just a one liner obvious fix. Now we have @oliver-sanders new bug though (2411), which i think is sufficiently serious to wait on ...
