Fix collection symbol initialization and update test assertions for ERC721 collection properties

- Corrected the initialization of the collection symbol in `ERC20FixedDenominationManager` to include a trailing comma for clarity.
- Updated test assertions in `EthscriptionsTokenTest` to reflect the new collection name and symbol, ensuring consistency with the latest contract changes.
