Search form redirects to the incorrect search page

When using the core search module, executing a site search from the search block form in the upper right hand corner redirects to the incorrect search page. The expected search path is "search/content", however the search is redirected to "search/search_facetapi". This is a plain search page with no facets. The bug is caused upstream in the Custom Search module by the issue reported at #1870868: The redirect in the custom_search_submit() function doesn't respect the "path" key in the hook_search_info() implementation..
