Previously, the query for the jobs page was really slow, as it checked the load_new_guix_revision_job_log_parts table for each job, doing a sequential scan through the potentially large table. Adding an index didn't seem to help, as the query planner would belive the query could return loads of rows, where actually, all that needed checking is whether a single row existed with a given job_id. To avoid adding the index to the load_new_guix_revision_job_log_parts table, and fighting with the query planner, this commit changes the load_new_guix_revision_job_logs table to include a blank entry for jobs which are currently being processed. This is inserted at the start of the job, and then updated at the end to combine and replace all the parts. This all means that the jobs page should render quickly now.
