Fix: Clear @ci_queue_requeued on DUP to allow proper finish

When dup.mark_as_requeued! is called, the DUP inherits @ci_queue_requeued=true
from the original. This caused the DUP to skip calling super(reporter) in finish,
leaving execution_result.run_time as nil. The JUnit formatter then failed when
trying to format the duration.

Now we explicitly clear @ci_queue_requeued in mark_as_requeued! so the DUP
goes through the normal finish flow.
