Copter: Fix zero throttle flip issue Stabilize 

The problem is that the init_targets is intended to ensure the
controller doesn't build up the I term when the throttle is low. Because
it is poorly named (or used) it have been written to do something else.
Here I change it to do what the code is trying to use it to do.
