fix: resolve extends layer document path

[cpreston321]

Issue

issue: #264

Context

This is a fix for extending multiple layers of nuxt and not just extending the srcDir

I really wanted to get this out as it is breaking my code for creating a re-useable template using the nuxt extends future!

if you need anything please let me know!

Thanks 💚

Here is a picture of it working as intended!
