Salesforce: don't stringify output

the salesforce adaptor will console.log LOADS of stuff. Half the adaptor functions log their results to stdout.

I am generally not a fan of doing this and I don't think it's inline with out best practice? We're normally a lot more cautious with data. So that's open for debate.

But as a minimum, we should not also stringify that output, as we do now:

 return connection.update(sObject, finalAttrs).then(function (recordResult) {
      console.log('Result : ' + JSON.stringify(recordResult));
      return {
        ...state,
        references: [recordResult, ...state.references],
      };
    });

We should trust the runtime to log an object and find a good way to render it. In Lightning's case, this (eventually) means making the object a collapsible line in the log viewer. In The CLI, it means (probably) using CLI options to control whether the output is prettified, or ignored, or written to disk, or whatever.

By stringifying the output though, the adaptor is taking a lot of control away from downstream services.
