Test new behavior in create_bolt11_invoice

Bolt11InvoiceParameters allows for setting currency and
duration_since_epoch. If currency is not set, test that the one
corresponding to ChannelManager's chain hash is usd. If
duration_since_epoch, is not set then highest seen timestamp is used in
non-std compilations.
