Duplicate symbols when using 'Go to Symbols' and 'Show all Symbols'

Setup
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
"allowJs": true
},
"exclude": [
"node_modules"
]
}

Create a single file with a single function.

Copied from original issue: microsoft/vscode#2172

I looked into it and the problem is that the function myFunction appears two times in the result. In the root and under the module node. See screen shot

May be this is a specific problem with commonjs which I use in the setup.

@vladima looked into it today, and the code generating the list is adding it twice. We should remove that duplication.
