wallet: check swap provider liquidity for send change to ln

Browse Source 
Check the swap providers liquidity as well if we try to send change to
lightning in `make_unsigned_transaction`. It is now expected that the
swap_manager is already initialized when calling
`make_unsigned_transaction`, otherwise no dummy output will get added.
