Currently, when retrieving a buildset from the API we also store the
builds that are contained in the buildset's API result in the redux
store. In case those builds were already present (because e.g. the
build page was visited before) they are overwritten but with less
information. This results in missing links and properties on the build
depending on how the page was accessed.
Since the buildset page is anyways using the builds that are contained
in the buildset directly and the build page fetches the necessary build
by itself in case it's not present already, we could simply remove the
relevant part in the fetchBuildset() action and avoid weird behaviour in
the UI.
