tbtc - Variable shadowing in TBTCDepositToken constructor

This variable is shadowed in the `TBTCDepositToken` constructor.\\n```\\nconstructor(address \\_depositFactory)\\n    ERC721Metadata("tBTC Deopsit Token", "TDT")\\n    DepositFactoryAuthority(\\_depositFactory)\\npublic {\\n    // solium-disable-previous-line no-empty-blocks\\n}\\n```\\n
Rename the parameter or state variable.
```\\nconstructor(address \\_depositFactory)\\n    ERC721Metadata("tBTC Deopsit Token", "TDT")\\n    DepositFactoryAuthority(\\_depositFactory)\\npublic {\\n    // solium-disable-previous-line no-empty-blocks\\n}\\n```\\n
