Fixes https://github.com/thoughtbot/administrate/issues/1643
When https://github.com/thoughtbot/administrate/pull/1618 was merged, some JS broke. One important piece of functionality that stopped working was "destroy" links.
We were using the JS-driven destroy links that are common in Rails. These work on links with the attribute data-method="delete", and show a confirm() box with text extracted from the attribute data-confirm.
You might be wondering why the specs didn't break... Well, it turns out that Capybara tries to be clever about these special attributes, even when using Rack::Test. As a result, tests passed even though the JS to drive the functionality wasn't working. To avoid this happening again, I have told Capybara to respect_data_method: false.
We'll still have to look into the issue that #1618 was intended to help with: how to integrate with both Webpacker and the asset pipeline. For now, this is a pressing problem, and this solution will make do.
The specs demonstrating the issue are taken from https://github.com/thoughtbot/administrate/pull/1688. Note one difference though: I'm passing the :js option as now Rack::Test won't try pretend that JS is available.
