Fix Model.scoped deprecation

[codez]

https://github.com/CanCanCommunity/cancancan/blob/master/lib/cancan/model_adapters/active_record_adapter.rb#L100 is still using #scoped. This causes a deprecation warning in Rails 4. Use #all instead if the Rails version is 4 or greater.

As far as I see this even causes an exception in rails 4.1.0.rc1 (undefined method scoped' for #Class:0x000001083e79a8` in that exact line). Perhaps #scoped will be completely removed in rails 4.1?

From what I understand, to support the functionality provided by scoped in Rails 3 and all in Rails 4, it needs to actually be replaced with where(nil).

I'll see about fixing this, I'm trying to get the testing framework for Cancancan turned around, since it was originally built with Supermodel and WithModel... both of which don't work with rails > 3.0

So I don't actually even have tests for rails 3.1, 3.2 or 4 yet.

Looks good, for me https://github.com/lacco/cancancan/commit/a98612ec98f800c464110355386337b29d9c725f works. So using all or where(nil) definitely seems to be the right direction.

Closing this as fixed in #21
