Stubs for shared view names

[landswellsong]

Because of Ecognize/django-openapi-gen#16 the measurement-detail view name is shared between Measurements, Quicklook and Download views, thus it's not possible to construct lists of Measurements by normal means.

After upstream is fixed, remove the stubs.

Manually adding the route gives:

<RegexURLPattern measurement-detail ^api/download/(?P<pk>[^/.]+)/$>
<RegexURLPattern measurement-data ^api/download/(?P<pk>[^/.]+)/data/$>
<RegexURLPattern measurement-quicklook ^api/download/(?P<pk>[^/.]+)/quicklook/$>

maybe there is a way to exclude the -detail bit. Anyhow this needs to be rethinked
