athena: Fix a couple of UX issues with entering password for networks.

. Make sure a network-row that has a password entry remains visible when
 the network list is refreshed.
. Make sure the password text-entry gets the focus when it is added to the list,
  to make sure that the virtual keyboard is visible.
