Fixes action_view issue where pages do not render due to NoMethodError

The detail_args_for method, without this fix, results in a NoMethodError there are no options being passed into it as it tries to execute the empty? method on a nil object.

The exact error that I used to get was the following...

Completed 500 Internal Server Error in 17ms
NoMethodError (undefined method empty?' for nil:NilClass):
