No errors are reported when a pipeline is not created

[ramonacat]

Problem

Steps

1. Put this in a .troy file:

define flow main
flow
  define connector console from stdio
  with
    preprocessors = ["separate"],
    postprocessors = ["separate"],
    codec = "string"
  end;

  define pipeline dumb
  pipeline
    select event from in into out;
  end;


  create connector console from console;

  connect /connector/console/out to /pipeline/dumb/in;
  connect /pipeline/dumb/out to /connector/console/in;
end

2. run with cargo run -- server run my.troy
3. Observe lack of error (note the pipeline is defined, but not created).

Notes

After a bit of investigation: It seems like the flow was not deployed. It would be useful if server run complained if no flows are deployed.
