fix: Home's list drops the previous network's rows after a network switch (closes #718)

A network switch left the previous network's rows or failure message in Home's
list until the new network's answer landed. Home now replaces them with
"Loading..." when it first draws on a new network. A redraw on the same network
keeps its rows.

Home, AddressDetail and AddressToken compared the page's network before reading
storage. A switch made in Settings could change the page during that read, and
the answer was still drawn. They now compare after the read, for an answer and
for a failure.
