[PATCH] views: Use select_related, not prefetch_related

[Stephen Finucane]

Now that there's a 1:N rather than N:M relationship between series and
patches, we should be using select_related rather than prefetch_related.

Signed-off-by: Stephen Finucane <stephen at that.guru>
Closes: #223
Fixes: 76505e91 ("models: Convert Series-Patch relationship to 1:N")
