7- New alghoritm for retrieving `token_iri`.7- New `token_uri` retrieval logic:

9      If the collection has a `url` property and it is not empty, it is returned.
10      Else If the collection does not have a property with key `schemaName` or its value is not equal to `ERC721Metadata`, it return an error `tokenURI not set`.
11
12      If the property `baseURI` is empty or absent, return "" (empty string)
13      otherwise, if property `suffix` present and is non-empty, return concatenation of baseURI and suffix
14      otherwise, return concatenation of `baseURI` and stringified token id (decimal stringifying, without paddings).
