[095] breed javascript is wrapped and escaped in certain cases

[olafmol]

when pasting this breed content from the workflows tutorials in de 095 UI editor:

name: hello_workflow
deployable:
  type: application/javascript
  definition: |
    'use strict';

    var vamp = require('vamp-node-client'); // required to interact with the Vamp API

    var api = new vamp.Api(); // a new Vamp API object

    // create a Vamp event - tag, value, event_type
    api.event('tag1:tag2', 'optional_value', 'hello_workflow');   
  

the javascript content is wrapped and escaped when saving and re-opening.

when removing all line breaks at the end, and then adding one line break, the formatting stays intact:

name: hello_workflow
deployable:
  type: application/javascript
  definition: |
    'use strict';

    var vamp = require('vamp-node-client'); // required to interact with the Vamp API

    var api = new vamp.Api(); // a new Vamp API object

    // create a Vamp event - tag, value, event_type
    api.event('tag1:tag2', 'optional_value', 'hello_workflow');
