Reproduction of Visual Studio issue 531237

Steps to reproduce:

1. Clone this repository
2. Run npm install in the /VSIssue531237 project folder
3. Open the solution in VS2017 and add a breakpoint on the console.log('Hello world'); line of index.js
4. Start debugging

Instead of the breakpoint being hit in index.js, a breakpoint is hit in node_modules/axios/dist/axios.js instead, as the debugger incorrectly determines that axios.js should be the startup script instead of index.js, as seen in the output in vscode-node-debug2.txt:

Launch: program 'D:\Projects\VSIssue531237\VSIssue531237\index.js' seems to be the source; launch the generated file 'd:\Projects\VSIssue531237\VSIssue531237\node_modules\axios\dist\axios.js' instead
