hook_install calls drupal_install_schema(), resulting in errors on install

I see the following error on install (via drush):

DatabaseSchemaObjectExistsException: Table tvi_settings already exists. in DatabaseSchema->createTable() (line 652 of /home2/ezheidtm/public_html/patdb1/includes/database/schema.inc).

Turns out that hook_(un)install was installing the schema, but this is no longer necessary: http://drupal.org/node/224333#install-schema

The attached patch removes the calls to drupal_install_schema() and drupal_uninstall_schema(). TVI then installs without errors.
