[ActivityManager] Fix NPE when start activity

Cherry picked from aosp.

Fixes bug 18593457.

Symptom:
NPE occurs in line 1184 (resultStack.sendActivityResultLocked)
because resultStack is null.

Root cause:
When starting activity with FLAG_ACTIVITY_FORWARD_RESULT flag,
the resultRecord could be updated, but the resultStack is not
updated as well. In that case, the resultStack is still be
null. The exception will occurs if the activity is not
granted to launch due to permission denied.

Solution:
Update resultStack when resultRecord updates.
