Subject: [PATCH] Make flu SystmOne codes based on dose sequence

In 1a2f96876702a4da675b5045ff2fd4904bc1ba34 I added the SystmOne codes
for flu under the assumption that the dose sequence would be `nil`, but
actually the dose sequence will instead be `1`. This fixes an issue
where the codes weren't coming through correctly.

Jira-Issue: MAV-1678
