Contract should call suscribeToGlobalEvents in constructor

[spacesailor24]

Doing the following seems to be problematic for Contract.clone and the Web3.ContractBuilder. In order to implement the following fixes with need to be investigated further than the scope of #5756

I think contractContext is just a copy of the context, which comes from self.getContextObject() here (any case), and subscribing doesn't have the effect we want.

@nikoulai contractContext is not a copy, it's a reference to the Web3Context the user is providing

const web3Context = new Web3Context('http://127.0.0.1:8545');
web3Context.defaultBlock = 'pending';

const contract = new Contract([], { syncWithContext: true }, web3Context);
console.log(contract.defaultBlock); // latest

web3Context.defaultBlock = 'earliest';

console.log(contract.defaultBlock); // earliest

(the console.log(contract.defaultBlock); // latest is a bug, as contract.defaultBlock should be pending as it's supposed to be set by web3Context)

The above code works as expected, but only if the following

if (contractContext !== undefined) {
    this.suscribeToGlobalEvents(contractContext);
}

occurs after the new line:

this.syncWithContext = (options as ContractInitOptions)?.syncWithContext ?? false;
