Use Xapian index path from app settings.

App settings should be accessed from current_app. It should not be hard-coded
to a variable in a module.

* gn3/db_utils.py: Do not import XAPIAN_DB_PATH from gn3.settings.
(xapian_database): Accept path argument.
* gn3/api/search.py: Import current_app from flask.
(search_results): Pass Xapian index path to xapian_database.
