NT-1756: Backing fragment crashes

[Arkariang]

📲 What

• Even though when we parse the response from Graph the BackingObject created should have been initialized properly, see

  android-oss/app/src/main/java/com/kickstarter/services/KSApolloClient.kt

  Line 630 in b1e6070

  return Backing.builder()

  
  We've been seeing crashes related with nullability issues, an wrong threads trying to Update the UI, none of it was reproduced locally, if you need more details go to Firebase Dashboard and look for all the crashes related to BackingFragment

🤔 Why

🛠 How

• Make sure no value from the ones above showed on the screenshoots is emited being null from the ViewModel to the Fragment

👀 See

BackingFragment.mp4

📋 QA

• Go to your profile and take a look into several of your projects already backed, the older the better
