upgrade electrum, do tests in nix

Now on nix env we provide the env vars of the executables needed for
integration testing, so we can enable tests.

To be coherent with the electrum nix version used, upgrade also the
autodownloaded one.

Note we have to change a test assertion, it seems electrum behaviour
changed, upgrading balances before confirmation.
