fix(mirror): ensure multiple runs (#9899)

Browse Source 
# Which Problems Are Solved

1. After second execution, mirror starts to fail because of Primary key
constraints on the events table. Because mirror always took the the
first `system.mirror.succeeded` instead of the newest one
2. Mirror panicked during migration of fields tables

# How the Problems Are Solved

1. Adjusted the database query to order descending and limit 1
2. added missing assignment

# Additional Changes

- detailed logging if the copy from statement failed.
