setupFiles do not transform by babel-jest

[MrGaoGang]

🐛 Bug Report

To Reproduce

when i config in jest.config.js, i set setupFiles is ["<rootDir>/test/setup"]
such as:

module.exports = {
  setupFiles: ["<rootDir>/test/setup"],
  moduleFileExtensions: ["js", "vue", "jsx", "json"],
  ...
}

but i see the setup.js do not transfer by es6, so i can't use 'import'

Yeah I had to add my file to transformIgnorePatterns which felt weird to me. 🤷‍♂

This seems like a potential regression. After bumping from 24.8.0 to 24.9.0, I began receiving the following error:

Downgrading back to 24.8.0 removes the issue. Trying to get a small reproduction together.

No fix yet?

For me, 24.8.0 also doesn't work. The latest version to work is 24.1.0.
