Update belongsTo and before/after callback calls to be compatible with Laravel 4.1

[brianwebb01]

This was a former pull request from Indatus:master now in its own branch Indatus:four-one-fixes

@igorsantos07 @laravelbook have you done testing against laravel 4.1?
I'm hoping you can either merge this PR or implement your own fix as 4.1 should be getting released over the next few weeks. And I'd like to start testing the new features on my dev site soon.
Thanks

Yes, this was created because of trying to use ardent with 4.1, however I did notice that there are issues with the ardent relationship declarations in 4.1. Looks like the relationships maybe aren't getting instantiated.

[igorsantos07]

@thomaswelton I'm not using Ardent actively anymore and I still couldn't find enough free time to give some love to the project... That's why we don't have tests yet.

And, just to make it clear, I haven't tested Ardent against 4.1.

Anyway, I'll accept the PR and release it as pre-release, like I did before. Thanks!

@brianwebb01 the method was renamed to belongsTobelongsTo... Please fix it before I merge (:

+1 I'm testing my app against 4.1 and ran into the issue with BelongsTo, would love to see the fix merged in so that I can start using 4.1

[mvalim]

any news on that?

[dschu-lab]

Yeah. Would you please merge the fix?

[webpatser]

yeah.. since it's official now ;-)

[igorsantos07]

Closing since @bexarcreative-daniel did a better job and fixed what this PR couldn't, as it was poorly written and also forgotten by the owner.
