[1.60 HF1] execute_custom_trade does not transfer funds when trading with wharfs

[morbideth]

As the title says the script command execute_custom_trade does not transfer funds when selling to a Wharf. Tested specifically the wharf in Holy Vision. This applies whether or not usecommandermoney is true, whether or not a trade offer is used, whether price or totalprice is used. Wares are transferred but credits are not. There are no errors in the debug log. The same script works correctly when trading with normal factories. I would assume this issue applies to shipyards, equipment docks, and possibly trade stations as well, but I have not tested it.
