The function transferERC721 works similar to the functions timeUnlockERC721 with timelocked NFTs.
However timeUnlockERC721 cleans timelockERC721s (delete timelockERC721s[key];), while transferERC721 doesnt clean timelockERC721s
This could mean that timelock keys could be used later on (when the NFT would have been transferred to the contract on a later moment in time). Also, the administration doesnt correspond to the available NFTs. Additionally doing a delete gives backs some gas (at least for now).
See Issue #19 for code referenced in proof of concept
Recommend checking if the timelockERC721s mapping should also be cleaned from transferERC721, if so adapt the code accordingly.
