Added appropriate response on contract-conflict during deposit
In case of a detected conflict during deposit, because
(merchant_pub, h_contract_terms) already existed, with different other
field values, we now provide the client an error response that contains
the h_wire. This way, the client can retrieve further details about the
conflicting transaction via
/deposits/$H_WIRE/$MERCHANT_PUB/$H_CONTRACT_TERMS/$COIN_PUB
Fixes #8002
