Android: Crash in Crashlytics stack track generation covers real error

[hansemannn]

We see an error that cannot be tracked because Crashlytics crashes before reporting it, during stack trace generation. A possible "fix" would be a null-check, although it's not clear why it's null here.

Works! Now we see the real crash (which now also does not kill the app directly):
