Tests are running in the local build folder

[gndelia]

If I run a build locally with npm run build, it will create a local copy of _esm. If I later run the tests, it will also read the tests on the _esm folder, which is the build folder.

See this example

✓ src/utils/fees.test.ts (24 tests) 2ms
 ✓ _esm/utils/fees.test.js (24 tests) 2ms

• Do not run tests on the _esm folder
• Do not copy test files on the generated build in the _esm folder!
