Admin Analytics: CSV Downloads broken #173
Description
In the admin analytics pages, you can download the complete results on most pages by clicking the "Download CSV" link in the bottom left corner. However, these links are currently returning errors.
The culprit seems to be related to the start/end time query parameters in the URL. In the download link the query parameters are start and end. If those get replaced with start_time and end_time, the download link works. But I'm a bit confused, and this needs further investigation because on the results page in the admin UI, we do use start and end (and the download URL parameters should generally match those). There's obviously a discrepancy between these parameter names somewhere we should cleanup.
We should also figure out why our test suite didn't catch this, since I recall fixing broken downloads before.
