Fix creating new activity instance when launching alias activity

New activity instance was being started on existing task while
starting alias activity because we used to correct the activity
intent for aliasing. Since the task record intent can now also
save alias activity component, they were evaluated as not using
the same intent filter.

Making sure they are evaluated as the same component as long as
they are having the same real activity.
