When click "Add network" to add a new network, user may ignore the "Hidden network" item, which is in "Advanced options". That will cause the added hidden network can not be connected. To improve it, move the "Hidden network" from last one to be first one. Bug: 135281908 Test: Check if the hidden setting spinner is the first one item in Advanced options.
