JavaScript 'Validatate file references' inspection

Hello!

I'm importing a function like this:

import { sendValues } from '../actions';

Thing is, "actions" is a folder containing index.js file in it, and before 2016.3 IntelliJ IDEA was able to understand that it needs to search for the function in index.js, so it correctly highlighted the function that I use in that file. Today I updated to 2016.3, and now IDEA shows me a warning "Cannot resolve file 'actions'" and highlights all functions in index.js as unused. Can I fix that somehow?
