Ensuring that disallowed types do not show up in search results

* There is a bug in the features export for apachesolr search
  that doesn't respect the types that shouldn't be indexed. This
  will ensure that those types don't show up in search.

Fixes #3206

They're constantly overridden because time-dependent items are included in the export.  https://www.drupal.org/node/1984502.  I attempted to use a few of these fixes, but unfortunately it's still not reliably using what's in features.
