Clear the index status when reindexing a project via gitlab:elastic:index_projects

Problem to solve

One our documentation, we suggested to re-index a project if we can't get any hits for the search term in the UI.

However, this won't always work if the IndexStatus record is updated for a specific project.

Proposal

Clear the index status within the rake task. This was suggested by @dgruzd in the slack thread.

Implementation plan

• modify the elastic.rake task index_projects to clear IndexStatus record from each project
• add a line before the ::Elastic::ProcessInitialBookkeepingService.backfill_projects! line that deletes the records for the current batch of IDs. It is important to clear the records before queueing the projects up for indexing.

        IndexStatus.for_project(ids).delete_all

        ::Elastic::ProcessInitialBookkeepingService.backfill_projects!(*Project.find(ids))

• add a new test to elastic_rake_spec.rb to verify that the records get deleted
