Summary: Finishing imports now occurs in Node instead of the data engine, which makes it possible to import into on-demand tables. Merging code was also refactored and now uses a SQL query to diff source and destination tables in order to determine what to update or add. Also fixes a bug where incremental imports involving Excel files with multiple sheets would fail due to the UI not serializing merge options correctly. Test Plan: Browser tests.
