RedisCacheStore - Fix Default Error Handler

* The `DEFAULT_ERROR_HANDLER` constant in
  `ActiveSupport::Cache::RedisCacheStore` contained references
  to an undefined argument `e`, which is supposed to refer
  to the `exception` parameter.
* Update the default error handler proc to correctly reference
  the `exception` parameter.
