Title: -[NSCachedURLResponse allHeaderFields]: unrecognized selector

Changes to -(NSDate *)lastUpdateDate method to prevent error.

When doing a pull to refresh the method above in RkabstractTablecontroller was giving me the following error

-[NSCachedURLResponse allHeaderFields]: unrecognized selector sent to instance 0xf486920

So I made changes to the code and the error is gone.

Hope this helps.
