MarketPlace.createMarket() calls Creator.create() which creates an instance of ZcToken and a VaultTracker. VaultTracker takes msg.sender as the admin. We know that if contract A calls contract B which calls contract C, msg.sender in contract C is the address of B i.e. the msg.sender in VaultTracker is the address of the creator contract. However, the creator contract is not able (and not supposed to) interact with the VaultTracker unlike the marketplace contract.
Modify the constructor of the VaultTracker contract so that the creator contract can pass in msg.sender (MarketPlaces address) to be used as admin.
