Fixing wildcard matcher

[Daanoz]

I've found an issue where nested wildcards are not matched. I've rewritten the folder matcher code to use recursion to find the correct folder.

Assuming the a folder structure like:

└── api
    └── lvl1
        ├── __p1__
        │   └──   lvl2
        │       ├──  __p2__
        │       │   └──   lvl3
        │       │       └──  GET.json (a)
        │       └──   1
        │           └──   lvl3
        │               └──  GET.json (b)
        └── 1
            └──   lvl2
                ├──  __p2__
                │   └──   lvl3
                │       └──  GET.json (c)
                └──   1
                    └──   lvl3
                        └──  GET.json (d)

Desired situation:
GET lvl1/1/lvl2/1/lvl3 => (d)
GET lvl1/8/lvl2/1/lvl3 => (b)
GET lvl1/1/lvl2/8/lvl3 => (c)
GET lvl1/8/lvl2/8/lvl3 => (a)

At the moment, if file (d) would not exist, it will result in a 404 not found when lvl1/1/lvl2/1/lvl3 is requested. Expected is that (c) would be returned. This is because the folder lvl1/1/lvl2/1 actually does exist, and the matcher doesn't look back once it finds an non existent folder.

With the changed code, the matching strategy will be as follows (first one that matches wins), stars indicate where a possible wildcard could be:

1. "/lvl1/2/lvl2/2/lvl3"
2. "/lvl1/2/lvl2/2/*"
3. "/lvl1/2/lvl2/*/lvl3"
4. "/lvl1/2/lvl2/*/*"
5. "/lvl1/2/*/2/lvl3"
6. "/lvl1/2/*/2/*"
7. "/lvl1/2/*/*/lvl3"
8. "/lvl1/2/*/*/*"
9. "/lvl1/*/lvl2/2/lvl3"
10. "/lvl1/*/lvl2/2/*"
11. "/lvl1/*/lvl2/*/lvl3"
12. "/lvl1/*/lvl2/*/*"
13. "/lvl1/*/*/2/lvl3"
14. "/lvl1/*/*/2/*"
15. "/lvl1/*/*/*/lvl3"
16. "/lvl1/*/*/*/*"
17. "/*/2/lvl2/2/lvl3"
18. "/*/2/lvl2/2/*"
19. "/*/2/lvl2/*/lvl3"
20. "/*/2/lvl2/*/*"
21. "/*/2/*/2/lvl3"
22. "/*/2/*/2/*"
23. "/*/2/*/*/lvl3"
24. "/*/2/*/*/*"
25. "/*/*/lvl2/2/lvl3"
26. "/*/*/lvl2/2/*"
27. "/*/*/lvl2/*/lvl3"
28. "/*/*/lvl2/*/*"
29. "/*/*/*/2/lvl3"
30. "/*/*/*/2/*"
31. "/*/*/*/*/lvl3"
32. "/*/*/*/*/*"
