In order to make the back button behave properly when coming from search
results or other intents, we must force IntentFilterActivity to have a
different taskAffinity so it doesn't launch the activities into the
same stack as the main application. This results in an empty back stack
for all Activities routed through IntentFilterActivity which is
exactly what we want.
