Remove network type from Apostille class constructor parameter

[Faiz Faidurrahman]

@gimyboya Apostille class can get Network type from account parameter.

it's to reduce redundancy and can remove some code validation like this

   if (generatorAccount.address.networkType !== networkType) {
      throw new Error('network type miss matched!');
    }

this will break a lot of code knowing that it will affect the constructor, however, I think it's still relevant to fix this
