Hans-Christoph Steiner 198ad843c1 fix crash when UpdateService receives null Intent
I have no idea what would send UpdateService a null Intent, but there have
been reports from ACRA:

ANDROID_VERSION=5.1.1
APP_VERSION_NAME=0.99.2

PHONE_MODEL=SM-G901F
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.content.Intent.getStringExtra(java.lang.String)' on a null object reference
