Hans-Christoph Steiner 7385d320b4 fix crash when UpdateService receives null Intent
IntentServices can get a null Intent if they are restarted after being
killed.  So this should be properly handled.

"[The intent] may be null if the service is being restarted after its
process has gone away, and it had previously returned anything except
START_STICKY_COMPATIBILITY."
