pass return type to fireplace

[clumsyjedi]

When I try and run a command that rewrites a file, like rename-symbol, I get this error:

Error: [object Object] is not ISeqable

Which stems from refactor-nrepl/fireplace#message returning a non-seqable entity. I'm not familiar with the inetrnals of fireplace or refactor-nrepl but I have learned from some other projects that passing v:t_list coerces the result to a seqable response.

(Pretty sure this is a fix for #31)

Yes, as far as I can tell CCleanNS works again. Thanks!
