* fix(utils): fix resources map becomes directory
closes#10187
Fixes the behavior of mapped resources generating extra directory, for example:
`"../resources/user.json": "resources/user.json"` generates this resource `resources/user.json/user.json`
where it should generate `resources/user.json`
This PR includes a refactor of the Iterator implementation which splits it into more scoped functions and relis on recursing instead of a loop which makes the code a lot more readable and easier to maintain.
