Update create & delete method for not to conflict existing controller cr...

This commit fixes #149

Ref : 
I am using wice_grid version 3.2.0.
I also have inherited resource gem to have CRUD methods predefined.

I wanted to use saved queries for wice grid. But when I click save its calling save method of actual controller which is causing all validation fire and saving query fails.

Can you please point easy way to fix this? Or else let me know if I need to override routes.
