title: No metadata for "User" was found using TypeOrm
body: <p>I'm trying to get a <a href="https://github.com/ripper234/typeorm-naming-strategy" rel="noreferrer">basic setup</a> working using TypeORM, and getting this error following the setup.</p>
  
  <p>Here is a REPL (just do <code>yarn install &amp;&amp; yarn db:dev</code> followed by <code>yarn db:migrate &amp;&amp; yarn start</code> to reproduce the error)</p>
  
  <pre><code>Inserting a new user into the database...
