"wrong number of arguments (given 1, expected 0)" on Index method

[acflint]

Hi @leknarf! Very excited to find this gem. Hopefully it will save me a ton of time building this functionality myself :) I ran into an error though. Maybe you can help.

As soon as I bundled the gem and launched my local server, I opened up activeadmin and the Index method gave me "wrong number of arguments (given 1, expected 0)" error. I'm using Rails 4.2.3, Ruby 2.3.3p222 and activeadmin 1.0.0.

Here's a screenshot of the error, but let me know if there's other info I can provide which might help.

Thanks!
