Debugger points to wrong file after upgrade to 1.60.0

Issue Type: Bug

Hi, I noticed that after upgrade to the newest version my debugger scripts start working incorrectly after upgrading to new version of vsocde.

The debugger script I use is responsible to open mocha tests written in typescript. It uses ts-node as transpiler so files are not compiled before running tests.
` { "type": "node", "request": "launch", "name": "Mocha tsc", "program": "${workspaceFolder}/node_modules/mocha/bin/_mocha", "args": ["-r", "ts-node/register", "src/*/.test.ts"], "console": "integratedTerminal",

  "internalConsoleOptions": "neverOpen",
  "protocol": "inspector",
  "skipFiles": ["<node_internals>/**/*.js"]
}`

In the current version when I set up breakpoint it break in a virtual compiled file on incorrect line: Screenshot 2021-09-08 at 15 08 51

While in 1.59 It was pointing to the source file correctly: Screenshot 2021-09-08 at 15 17 32

What I noticed is that usage of reflect-metadata has an impact on it, as it works correctly in projects where I don't use it.

Here is a repository with minimal source code that reproduces issue: https://github.com/krystianolech/vscode-issue-132644
