Title: 20479903 duplicate lanes with multiple sequencing requests

[fixes 20479903] De-duplicate lanes that have multiple sequencing requests

Lanes should not have multiple sequencing requests, which has occurred
because we duplicated the requests that were in multiple batches. This
ensures that each lane that has multiple requests leading to it get
duplicated.
