Import paths / file names with "type extensions" do not work.

[ChristianUlbrich]

If an import contains additional dots, i.e if you are using a _"type exentensions"_™ this plugin will not add the actual extensions.

import { somethingBackFromOther } from '../lib/something.lib'should be transformed to import { somethingBackFromOther } from '../lib/something.lib.js', but it stays untouched.

However those filenames are quite common in a lot of frameworks (i.e. component.style.ts, component.test.ts, ...), actually the default extension for Jest tests is test.js (and thus in typescript test.ts).

I have added test cases at least for the imports at https://github.com/ChristianUlbrich/babel-plugin-add-import-extension that will fail.

This needs some consideration on how to combine this with the ability to replace an extension. I skimmed through the code and for me personally it is pretty dense (asi, nested destructuring, no comments, ...) so I can't come up with an easy fix w/o re-writing larger parts of it. Maybe @karlprieb can fix this in an instant. :)

Sorry @ChristianUlbrich i didn't have time to fix this, can you open a PR adding the test cases? I'll probaly continue the work from your branch :)
Thank you!
