Taxonomy/field base included in feature breaks install profile if profile invokes another install profile that creates those bases/taxonomies.

I think there's a problem with Features in that if you have a feature that is a dependency of an install profile (designated the primary install profile), and that primary profile in turn invokes another install profile (in our case it invokes the standard profile installation), and that feature has field bases/taxonomies that were created by the standard install profile, then the build process explodes when attempting to install the primary profile like so:

WD php: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'tags' for key 'machine_name': INSERT INTO          [error]

Drush command terminated abnormally due to an unrecoverable error.

Steps to replicate:

1) Create a feature that includes field bases or taxonomies defined by the standard install profile. An example would be to include field base field_tags and also the tags taxonomy.

2) Download the feature. Add this feature as a dependency to a custom install profile.

3) Have the custom install profile invoke the standard install profile in it's install hook, like so:

function my_profile_install() {
  // run the standard install first
  include_once DRUPAL_ROOT . '/profiles/standard/standard.install';
  standard_install();
}

4) Install site using the my_profile install profile.

5) Verify that the installation process errors out, specifically complaining about taxonomy/field bases already existing (if installing using drush si, you'll see the error posted above).
