AR.each_instance doesn't work and permit access to instance fields

[RaVbaker]

It's related to this problem from Rails: rails/rails#15107

Because of the row.symbolize_keys line ( #61 ) instantiate from line #173 is not properly assigning attributes.

I will write a tests and temporary fix for it. At least until it's not fixed in Rails 4.

@RaVbaker thanks! I was up late last night chasing that down, and suspected it may be an issue with ActiveRecord ~ 4.1, and was trying to pinpoint the release with the regression.

Chasing internal ActiveRecord API changes is tough for all these plugins trying to add enhanced features. Lately, I've been trying to find a sharding library that works with 4.1, and most have fallen behind and aren't even supporting 4.0 yet. I know their pain. :-)

I'm coding a fix for it now. It will be with a bit of refactor of the gem.

@RaVbaker Thanks for the good work there. Unfortunately, I felt the library needed a bigger refactor to support these features. The v0.5 branch now works with Rails 3.2 through Edge (4.2?) Since I wrote this 6 years ago, Rails has evolved a lot, and each minor release brings breaking changes. I hope this new structure better integrates into the upcoming versions of Rails (including Aaron's "Adequate Record"). I looked at your code here for ideas, so it has been very useful!
