Don't update task to return to type for last task over home

Resizing docked stack to fullscreen size results in dismissal
of docked stack and moving of tasks to fullscreen stack.
When tasks, which were originally launched from home or recents,
are inserted on top of fullscreen stack, their mTaskToReturnTo
value was overwritten.
This CL doesn't allow to overwrite this field of task if there
is no next task in stack and it was launched from home or recents.
