misleading error trying to select from non-existent series

[jvshahid]

graphite> select * from this-series-DEFINITELY-doesnt-exist
graphite> ✘ Error: Couldn't look up columns for series: this-series-DEFINITELY-doesnt-exist

error should be something like "series 'this-series-DEFINITELY-doesnt-exist' not found"

#1004 is about existing series that don't have data for the requested timeperiod.
this issue (#778) is about series that don't exist at all.

if i understand correctly, now if you select a series that doesn't exist you get an empty response, I think it would be better to return an error that the series doesn't exist at all.

That makes sense. Reopening

/cc @pauldix @toddboom are you guys fine with this change ?

[toddboom]

@jvshahid In keeping with the current error message style, can we make it:

Couldn't find series: series-name-here

Or tell me it's fine as it is. ;)

Looks good. I'll merge as soon as Travis finishes.
