this adds an implicit dependency on the `hqcase` app in HQ. while this is technically fine now since HQ is now the only consumer of this repo, it is unfortunate to introduce this as it will, for example, break travis if anything tries to call this. the long term solution would be to eliminate `hqcase` entirely, but the short term could be to move this one view into casexml (presuming it makes sense for it to be there)
