Fixed unwrap on None when importing embedded assets

[443eb9]

Objective

• Fixes unwrap on None problem when importing a embedded asset. Just a slight change.

Solution

• Use the 0th instead of 1th in macro embedded_path!
• Before:
• let after_src = file!().split($source_path).nth(1).unwrap();
• After:
• let after_src = file!().split($source_path).nth(0).unwrap();

---

• The embedded assets can be now imported correctly.

I think this deserves a more comprehensive fix. I'm working on another PR.
