Fix repo connect progress bar clobbering output (#1990)

## Description

The Backup/Restore operations ensure progress bars are completed before logging to stdout.
When a progress bar was added to repo connect - this is outside of that scope and ends up not getting
shutdown correctly.

This fixes that by adding a `observe.Complete()` in `Connect`.
