Downloading OBL logs hangs forever

[juliatuttle]

When I try to download an OBL (of all my communication or just one session), the modal hangs forever at "Generating log files for download...", until I click "Cancel" or outside the modal.

It looks like the Exporter module returns a JSON dictionary with keys for url, path, and uploaded, but the download-log modal controller expects the result to be a plain string containing the URL, crashes when it tries to split an object, and never updates the modal status.

I've managed to satisfy my own desire for logs by opening Chrome DevTools, finding the progress response, and pulling out the URL, so I know the actual log export and upload process works -- it's just handling the response that seems to be broken. Please let me know if there's anything else I can do to help debug or fix this, and thanks again for all your work!
