dev: update the json abi to uniformize class hash used by madara and mock

[j1mbo64]

Madara and Mock don't use the same contract ABI (some have line breaks), so the class hashes are not the same between Madara and Mock.

Do you want Mock to use the same genesis.json ? Or Mock to use his own genesis.json but same contract ABI as Madara ? Or just update Mock contract ABI ?

Can you directly assign me to the task ?
