bug
What is the current behavior?
Using babel-plugin-lodash, collectCoverage enabled and a lodash function as show below imported from test file, results into an error.
import { flow, flatten } from 'lodash/fp'
// export const testFunction1 = flatten
export const testFunction2 = flow(flatten)
example#testFunction1 npm test
will output
/home/nam/projects/jest-babel-lodash-issue/src/example.js:3
var testFunction1 = /* istanbul ignore next */exports.testFunction1 = ();
^
SyntaxError: Unexpected token )
example#testFunction2 npm test
will output
ReferenceError: /home/nam/projects/jest-babel-lodash-issue/src/example.js: Container is falsy
at NodePath._replaceWith (node_modules/babel-traverse/lib/path/replacement.js:170:11)
Removing collectCoverage
from package.json
lets the tests run without failure.
Removing babel-plugin-lodash from .babelrc or importing directly from lodash also runs without failure.
If the current behavior is a bug, please provide the steps to reproduce and either a repl.it demo through https://repl.it/languages/jest or a minimal repository on GitHub that we can yarn install
and yarn test
.

What is the expected behavior?
Test should run without errors.
Please provide your exact Jest configuration and mention your Jest, node, yarn/npm version and operating system.
Ubuntu 16.04.1 LTS, node v6.11.0 npm 3.10.10 also tested with node v8.1.3 npm 5.0.3
