fix: a popup reload no longer logs the requests it cancels, except on the transaction detail and confirmation screens (closes #475)

The transaction lists and ENS name lookups on the address and token
screens, the address scan after a wallet is created, the endpoint checks
in Settings, the wait screen's receipt check, the Send screen's Max fee
estimate and the token lookup on both add-token screens now check the
signal the popup aborts on pagehide before reporting a failed request.
scanForAddresses(), resolveEnsNames() and lookupTokenInfo() take the
signal.

End-to-end tests reload the popup on the address screen and during the
address scan with their requests held. Jest tests show each of these
reports a real failure and stays silent once the popup has closed. The
transaction detail and confirmation screens are left out: they discard
the popup context that carries the signal.
