title: Crashlytics log not sent
body: <p>I have Crashlytics properly configured in my app. I can see crash reports.</p>
  
  <p>I tried to add a custom log to the crash reports but I do not see anything in the report. 
  I tried to move the log out of the uncaughtException handler and in that case I see the logs.</p>
  
  <p>So if I log while the application is running properly then I see the logs in the crash report when the application crashes but if I try to add a log in my uncaughtException handler these logs are not shown.</p>
  
  <p>is this the proper behaviour?</p>
  
  <p>I'm on Android.</p>
  
  <p>To log I just use:</p>
  
  <pre><code>    Crashlytics.log(myLog);
  </code></pre>
  
  <p>myLog is a non-null non-empty string (I checked it)</p>
