Refactor to PSR2 and simplify accessor

[niladam]

I basically, applied some simple styling to this and i refactored the getUrlAttribute so that it's easier to read and a little bit simplified it :)

I think the entire codebase should be refactored to PSR2 so that it matches Laravel's style. You could do this via php-cs-fixer. I think this might get you on the right path as i see you're using PhpStorm.

Codebase should be refactored to PSR2 to match Laravel's code styles definitely but I'm used to having this kind of code style. It's more readable for me. In some of the next versions, I will refactor codebase to PSR.
