Do not unparcel bundle from application in LaunchActivityItem

The bundle fields may contain custom Parcelables. And Bundle#size
will call unparcel that causes BadParcelableException from
LaunchActivityItem#hashCode and LaunchActivityItem#equals.

Since the bundle fields of LaunchActivityItem may not be significant
for being the accurate identity of the item, the bundle fields can
be treated roughly (empty or not) to avoid unparceling.
