Update dummy app environment to silence warning

We were getting the following warning while running tests. We just needed to
set the new configuration option.

```
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

  * development - set it to false
  * test - set it to false (unless you use a tool that preloads your test environment)
  * production - set it to true
```
