Problem & expected behavior (under 200 words)

• What happened

  When using nyc and tsx the instumented files cause an error:
  Cannot read properties of undefined (reading 'startsWith').

  I think this line is causing the issue, as modules don't always have an id:
  

  tsx/src/cjs/api/module-extensions.ts

  Line 107 in 28a3e7d

  if (module.id.startsWith('data:text/javascript,')) {

• How to repoduce

  Use stackblitz or manual steps:

  npm init -y
  npm i tsx@4.19.2 nyc@17.1.0 --save-dev --save-exact
  echo "node-options=--import=tsx" > .npmrc
  echo "{\"all\": true, \"sourceMap\": true, \"instrument\": true}" > .nycrc.json
  echo "console.log('hello world')" > dummy.js
  npx nyc node dummy.js
