Adds IA instance inside the RecordSource.import() method - I wanted to make sure that IA check can only run if Hathi check has been completed first, so there's an if block nested inside another if block.
Removes the check_ia_path from the routes, Tasks Controller, and associated tests
Removes the IA check button
Updates the alert/info about how the import/checks work
