title: I can't specify a new region for cloud functions
body: <p>I changed the location of my cloud functions from "us-central1" to "europe-west1" but I can't change the location of my functions on the client side which is a compulsory step for it to work according to the documentation.</p>
  
  <p>(IDE tells me that no argument is expected on 'functions' when i do:</p>
  
  <pre><code>firebase.initializeApp(config).functions("europe-west1");
  </code></pre>
  
  <p>As an attempt to solve my problem I updated the three dependancies below with no result.</p>
  
  <p>firebase-tools@latest
  firebase-functions@latest 
  firebase-admin@latest</p>
  
  <p>The problem is still here.</p>
