Subject: [PATCH] Fix memory leak in Bluetooth settings

Bluetooth settings screen has two categories. Each category should call
removeAll() method to unregister a callback from CachedBluetoothDevice.
But the method is not called for mPairedDevicesCategory.

Bug: 30004142
Test: manual - connect to Bluetooth device and then
               open and close Bluetooth settings screen repeatedly
