Putting icon on uncovered lines

[agarrharr]

For some reason, it is putting the icon next to any new lines I add, even if they aren't covered. I'm putting brand new functions in a file and never calling those functions. After jest --coverage runs, the plugin puts a green icon next to the lines in that function.

I also checked out that file and the s key for that file said 0.

"/file/path.js": {
  "path": "/file/path.js",
  "statementMap": {
    ...
    "203":{"start":{"line":389,"column":14},"end":{"line":389,"column":15}}
    ...
  }
}

"s": {
  ...
  "203":0,
  ...
}

@Aharris88 Thanks for reporting. Seems there is a bug in computing the covered lines from statement map. I will look into this weekend. Pull requests are welcome :)

I'm guessing the bug has to be here, but I'm not sure what the problem is. It looks good to me.

Yes, that's right. I am working on it, should be fixed soon.
