Issue #237: error loading older examples

[Cthomp7]

Error was coming from line 342 this._text.code = null. It was unhappy about it being null, so I set it to an empty string. #237

Also after choosing yes!, I have it hide the convo. The ' e.goTo('loaded-json')' wasn't referencing anything.

@Cthomp7 this looks good (functionally speaking), but there are linting issues in the convo file:

• the global comment on top is /* global utils, NNW */ but should now be /* global NNE */
• there's also lots of extra spaces (tabbing with 4 spaces vs 2, as well as an extra space at the end of line 6
• line 5 has a template literal string which should just be a normal string
• bracket at the end of line 17 should be on the next line
• end of file should have a line break

here's a version that should pass the linter u can copy+paste ;)

/* global NNE */
window.CONVOS['demo-example-maker'] = (self) => {
  return [{
    id: 'before-loading-json',
    content: 'Looks like you want to upload a new example. Are you sure you want to overwrite your current session?',
    options: {
      'yes!': (e) => {
        self._uploadJSON(self.loaded)
        e.hide()
      },
      'load it in a new tab': (e) => {
        const l = window.location
        const str = JSON.stringify(self.loaded)
        const url = `${l.protocol}//${l.host}/?dem=true#example/${NNE._encode(str)}`
        window.open(url, '_blank')
      },
      'oops, no thank you': (e) => e.hide()
    }
  }]
}

@nbriz Copied and pasted :) Thanks a lot! I have a sticky note that says "make sure your code is up to STANDARD!" Need to get better at remembering that haha

@Cthomp7 i'm still getting the following linting errors:

• there's also lots of extra spaces (tabbing with 4 spaces vs 2)
• end of file should have a line break

i'm guessing ur editor might be auto-formatting things when u save, so to avoid too much back/fourth i'm gonna merge this && then just clean it up in one of my next updates :)
