title: FirebaseRemoteConfig.getInstance crashes with NullPointerException
body: <p>I'm seeing bunch of crashes inside Crashlitics which are coming from most recent <strong>Firebase 15.0.0</strong> on attempt to get FirebaseRemoteConfig</p>
  
  <pre><code>Caused by java.lang.NullPointerException
  Attempt to invoke virtual method 'void com.google.android.gms.internal.config.zzar.zzc(long)' on a null object reference
  com.google.firebase.remoteconfig.FirebaseRemoteConfig. (Unknown Source)
  com.google.firebase.remoteconfig.FirebaseRemoteConfig.getInstance (Unknown Source)
  com.google.firebase.remoteconfig.FirebaseRemoteConfig.getInstance (Unknown Source)
  </code></pre>
  
  <p><code>FirebaseRemoteConfig.getInstance</code> is called during <code>Application.onCreate</code> and it worked fine on all previous versions.</p>
  
  <p>Build:</p>
  
  <pre><code>implementation "com.google.firebase:firebase-config:15.0.0"
  classpath 'com.google.gms:google-services:3.2.1'
  </code></pre>
  
  <p>Does anyone see it? Any solutions or workarounds?</p>
  
  <p>P.S. I've sent bug report to firebase team via <a href="https://firebase.google.com/support/contact/bugs-features/" rel="noreferrer">https://firebase.google.com/support/contact/bugs-features/</a>
