Ticket #49761 - Fix CI test suite issues
    
    Problem Description:
    tickets/ticket47966_test.py is FAIL in CI nightly runs
    
    Fix Description:
    Remove tickets/ticket47966_test.py as it has already been ported to vlv/regression_test.py::test_bulk_import_when_the_backend_with_vlv_was_recreated
    Add a blank line in test header to avoid potential problem when parsing
