Merge JoinMarket-Org/joinmarket-clientserver#1599: Use `coins_to_satoshi()` and `satoshi_to_coins()` from `bitcointx` everywhere

395050cfa4 Use coins_to_satoshi() and satoshi_to_coins() from bitcointx everywhere (Kristaps Kaupe)

Pull request description:

  It's bad to have different functions for the same thing, `coins_to_satoshi()` were already used in some tests.
