Android: Fix crash in QBluetoothLocalDevice ctor due to Java exception

In general BluetoothAdapter.getDefaultAdapter should not throw an
exception. If the device does not support Bluetooth the function should
return a null reference only. However some devices throw a
RuntimeException as well. We need to catch it to prevent unwinding of
the stack.

At the same time the patch simplifies the code by using
QAndroidJniObject where possible.

[ChangeLog][QtBluetooth][Android] Fixed crash in QBluetoothLocalDevice
ctor on some devices due to a platform exception in
QBluetoothAdapter.getDefaultAdapter().
