[DO NOT MERGE] Fix NPE caused by an install flow where we decode the LauncherActivityInfo

but we don't fill in the data Intent.

Adding do not merge tag here, as we want the fix to have soak time in QPR2 ASAP.
The fix for master will be added to master branch next time we drop code from
ub-launcher3-master.
