Fix V45 migration to include initial population of jobs_fqn table

[collado-mike]

Problem

The V45 migration as is will cause no jobs or runs to be visible until the jobs_fqn table is populated. This adds a quick step to the migration to do the initial population, relying on the trigger function to handle new jobs as they are written.
