0-sat output when buying 0 value listing

[jadwahab]

tried to buy 0 value listing on market page and get the following error:
unexpected response code 500: 64: dust

Expected behaviour:

• since item is listed for 0 value, then we just take the price (which is 0) and and create and output for that, hence the 0 sat output that the node is complaining about (dust error)

Example tx:
