Prefer .headOption over .head

[davidfurey]

There should always be an element if the main media exists, but we have found one example where this wasn't true in Pre-Publication/Preview content.

This should hopefully fix an issue that we have seen in production (well, preview)

Stack trace that this should avoid:

Thanks for the review. I'm hoping this might finally be a change that sbt-version-policy considers to be patch only.
