Upon creating updates to my Sketch Plugin, no updates go through
As I update the files in my sketch plugin, no updates occur. When I update the manifest.json file, the information isn't updated. 

When I change the js file, nothing gets executed: 

```
{
  "identifier" : "unique.line.testing",
  "version" : "1.0",
  "description" : "This description for the tool",
  "name" : "Tool Name",
  "compatibleVersion": 3,
  "bundleVersion": 1,
  "commands": [
    {
        "script" : "currentFile.js",
        "handler": "handlerForFunction",
        "name" : "handler for function",
        "indentifier" : "handlerforfunction"
    }
  ],
  "menu": {
    "items": [
      "handlerforfunction"
    ]
  }
}
```

For instance, the menu isn't showing in the top of the nav in the plugins menu. I've run `npm run watch`. Anyone know what seems to be the problem? Maybe I should just do this all manually since this is just causing more problems?
