Subject: [PATCH] Remove redundant enableSearchInput function

enableSearchInput was called from two places:

- setupSearchLoader
- addSearchOptions, which is itself called from setupSearchLoader only

This commit can safely get rid of the addSearchOptions calls entirely,
and since the setupSearchLoader call is immediately preceded by other
method calls on search_input, there's no need to check if it's set.
