Lowering the scope of dkan_api.

[thierrydallacroce]

After checking out this branch, when clearing cache, drush complains with:

The service "dkan_lunr.search" has a dependency on a non-existent service "dkan_api.controller".

I will try to comment it out and proceed.

• GET /api works
• GET /api/1 works
