title: "No provider for TranslateService" error somehow connected to npm install
body: <p>With <a href="https://github.com/dancancro/great-big-example-application/tree/dashboard" rel="noreferrer">my Angular+Webpack+JHipster+yarn project</a> I get the following error. Then I delete <code>node_modules</code> and run 'npm install`, and it goes away. Then I do this and that and it comes back. How come? I'd like to not have to do that. The TranslateService listed in the error is one provided by a library, not one of my own, and is used in <a href="https://github.com/dancancro/great-big-example-application/search?utf8=%E2%9C%93&amp;q=TranslateService&amp;type=" rel="noreferrer">three generated components</a> of my project that I did not write.</p>
