Elasticsearch filename attribute contains full path - consider changing to proper filename
Currently we add the full path to our blobs that get indexed inside elasticsearch despite having a
ElasticSearch::GitLab::LiteBlob#name method that extracts the filename for us. This causes
filename filter to seem to be broken to our users (see #7408)
We should probably fix this, but I wanted to make sure there wasn't a reason for this first
cc/ @nick.thomas as it seems this came from a gem we imported?
