Fixes two bugs with findLastActiveTasksAndRunCallback()
This CL changes findLastActiveTasksAndRunCallback to return a fixed array rather than an ArrayList.
1) This fixes a (minor) crash with app pairs, where we performed get(0) on an empty array when no running tasks were found.
2) This also fixes a live bug where app pairs would launch apps in the wrong order if app 1 was not found in running tasks, but app 2 was.
The function should be more robust now, preserving the indexing of the input keys.

Test: Clear all tasks from Overview, launch an app pair, launch succeeds
