Fix deadlock in LocalBluetoothManager
Following deadlock exist in previous code:
1. Main thread
Device.refresh()->Device.dispatchCallback()->Lock callback->(handle
callback in systemui)->DeviceManager.getDevicesCopy()-> try lock
deviceManager
2. Bg thread
DeviceManager.onUuidChange()->Lock
deviceManager->Device.refresh()->Device.dispatchCallback()-> try lock
callback
This CL remove sychnorized method in DeviceManager to unblock this
deadlock. Since UuidChange can only happen in bg thread, we don't need
this extra lock in DeviceManager.
