title: Leakcanary crashes with Google's Firebase
body: <p>When processing a leak, I get a <code>java.lang.IllegalStateException: FirebaseApp with name [DEFAULT] doesn't exist.</code> inside my <code>Application.onCreate</code>. From what I understand, this happens because LeakCanary creates my application class without all the Google Play Services stuff and Firebase cannot initialize successfully. Any ideas how to fix this?</p>
  
  <p>Edit: 
  I'm using <code>leakcanary-android:1.4-beta2</code> and this happens after dumping the heap.</p>
