urlutil returns corrupted url if url contains invalid chars in path

# Description

- `https://scanme.sh/%usdf%0D%0A` is a invalid url since `%u` is not a valid encoding character
   - `url.URL` returns error if above url is given 
   - `utils/url/URL` was designed to allow such cases
- However it returns a corrupted url instead of valid one for this case i.e
```
https://scanme.sh/https://scanme.sh/%usd%0D%0A
```
