A balance refresh that returns now draws the balances on AddressDetail or
AddressToken again when that screen is up, not only the wallet list. Their
transaction lists are left alone.
Every add path on AddToken and SettingsAddToken tracks a token through
trackToken(), which gives the tracked record `balanceNotFetched: true`. While
the field is set, the token's line reads `quantity unknown` instead of 0.0000.
The popup's refresh deletes the field once it has read the token's balance at
every address. refreshBalances() now resolves with those tokens. The field is
part of the tracked record, so removing the token removes it, and each network
keeps its own records.

When the background saves a network switch after the user approves a
site's request, or another popup page saves one, an open popup takes the
new network from the stored record inside a save, holding the lock, and
checks the record once at start-up for a switch saved before it
listened. The network it takes is not counted as the popup's own change,
even when that save fails to write. It then leaves the page as a switch
in Settings does. A switch in Settings is now made inside its own save
too, so one picked while a follow waits for the lock is made after it.
The popup never switches the network itself.

The popup's doRefreshAndRender() and the background's backgroundRefresh()
each note the network a refresh starts on and write its balances only if
that network is still the active one when the requests return. Otherwise
nothing is written and lastBalanceRefresh stays as the switch left it. The
background checks inside updateState(). The popup refreshes a copy of its
wallets and copies the results onto `state` from inside its save, under the
lock, only if both its own network and the stored record's still match, so
a switch the background makes is caught too. saveState() takes an optional
function, run there on the stored record before the page's state is
compared, that may change `state` or return false to cancel the write.
