title: Firebase Phone Authentication not showing app name
body: <p>I have added firebase phone authentication to my android app.
  It worked well, but the the app name is not included in the sms verification message as it appears in the sms template in the firebase console:
  (%LOGIN_CODE% is your verification code for %APP_NAME%.).</p>
  
  <p>The message I receive looks like: 
  (%LOGIN_CODE% is your verification code)</p>
  
  <p>I have this problem for both debug and release versions of my app.</p>
  
  <p>So, how to add the app name to this message.</p>
