Build correct basenames for title search results

The "basename" here needs to be the full path without the trailing
extension, instead of stripping the leading path as well.

This was previously fixed in 2f36efa0 inside the view, but the
problematic code was still present in FoundBlob, and the corresponding
spec didn't actually use a child wiki page to properly verify the fix.

app/views/search/results/_wiki_blob.html.haml

 - project = find_project_for_result_blob(projects, wiki_blob)
 - wiki_blob = parse_search_result(wiki_blob)
-- wiki_blob_link = project_wiki_path(project, Pathname.new(wiki_blob.filename).sub_ext(''))
+- wiki_blob_link = project_wiki_path(project, wiki_blob.basename)
 
 = render partial: 'search/results/blob_data', locals: { blob: wiki_blob, project: project, file_name: wiki_blob.filename, blob_link: wiki_blob_link }
