[BUG] Not able to load types to .js files imports

[HonzaTuron]

First thing first, thank you for your great library! Anyway, I'm struggling with setup for .js files. Description below.

Describe the bug
When I set default file as JavaScript, ts definitions are downloaded, but not applied for js imports (import is marked as unresolved)

To Reproduce
Load js file with some npm import

Expected behavior
import is correctly loaded from ts definitions
