Function register_contract in wasm module should behave more like real blockchain

[DariuszDepta]

let contract_addr = self.register_contract(
    storage,
    code_id,
    sender.clone(),
    admin.map(Addr::unchecked),
    label,
    block.height,
)?;

For the same sender, checksum / code id and salt, the implementation above should generate the same address and fail, just like here.
