Use to_param instead of id method to route to a singular resource.
Some ORMs/ODMs return a Symbol for primary key, therefore we must call #to_s (or interpolate as was the case before @Daxter's 5a736047)
Do not assume that a #foo_id method implies a #foo method (fixes @Daxter's regression in 600b5398)

improve test perf by deferring garbage collection

Our tests run noticeably faster by only running garbage collection every 15 seconds.

modularize the search method dropdown for the filter form
fix Rails 4 problem with form builder ("undefined method `upcase'")

In Rails 4, ActiveRecord::Base#model_name no longer returns a string, but an ActiveModel::Name object, see https://gist.github.com/brupm/4544950. Calling #to_s on this object is a Rails3-compatible workaround for this change.

Include JS in layout with rails helper
remove redundant set of tests

This code almost exactly mirrors the tests abve it. The only difference
being that this uses `button_html` while the other uses `label` when
dealing with `f.action`.

We shouldn't be testing Formtastic's public API, so I'm removing the
second set of tests.
add test to ensure that form attribute labels are translated

Assuming Foo HABTM Bars, the below now works as you'd expect:
```ruby
ActiveAdmin.register Foo do
  filter :bars
end
```
