In https://github.com/OpenZeppelin/openzeppelin-contracts-ethereum-package/pull/76, we are rearranging the erc721metadata contract storage layout, so the new variable is added at the end. This commit applies the same change to the vanilla contracts repository, so migration from 2.5 to 3.0 is easier for users using the transpiler.
