Importer creates multiple FamixTypeScriptAccess for same variable when variable used multiple times in a method

[fuhrmanator]

In version 2.0.3, importing the project associated with this method:

https://github.com/gothinkster/angular-realworld-example-app/blob/2555e2f86dd85f6b9e3a34e720bb46689c8646f8/src/app/features/article/components/article-list.component.ts#L74-L98

results in multiple Access elements (e.g., one for each time the limit variable (Property) is accessed in the runQuery() method):

  {
    "FM3": "FamixTypeScript.Access",
    "id": 2724,
    "accessor": {
      "ref": 674
    },
    "variable": {
      "ref": 667
    }
  },
  {
    "FM3": "FamixTypeScript.Access",
    "id": 2725,
    "accessor": {
      "ref": 674
    },
    "variable": {
      "ref": 667
    }
  },
  {
    "FM3": "FamixTypeScript.Access",
    "id": 2726,
    "accessor": {
      "ref": 674
    },
    "variable": {
      "ref": 667
    }
  },
  {
    "FM3": "FamixTypeScript.Access",
    "id": 2727,
    "accessor": {
      "ref": 674
    },
    "variable": {
      "ref": 667
    }
  },

Opening the model in Moose results in a crash, with a SlotNotFound: Could not build slot named 'accesses' because the assignated slot was not found in the image. (which seems unrelated to the bug, but I traced it to the processing of a FamixTypeScript.Access element.

Looking at VerveineJ models, I only see that one Access is generated per method-variable pair, regardless of the number of times there's an access in the method.

It's easy to make a test for this in the ts2famix importer.
