Refactor guest routes

[nekitbr]

This PR intends to refactor the way whitelisted routes are unprotected.
After the merge, we can declare all whitelisted routes in one place and the filter will behave accordingly.

These issues were created before the original solution on the commit dfee1e5
closes #8
closes #12
closes #20

The previous solution was bad and didn't user the antMatcher from the middleware RequestMatcher. This needs to be done because the String[] of routes is meant to be used there, thus we should abide by it's rules.

Hi @nekitbr ,
First off, thank you for your contribution and the effort you've put into this pull request. It's great to see your engagement with the project.
I really like the way you think about this to whitelist and improve the performance of the code.
I will accept this PR and showcase in the next youtube video before merging it.
I'm telling you this because I want always my code to be consistent with the videos, that is the only reason to postpone accepting your PR.

Also, I want to mention that your Github username will be on the video. I hope this is okay with you. Otherwise, please let me know so I can sensor it in the video
