Beaker: dat site conversion results in blank drives

[dasanchez]

Clicking the "Convert" button results in an empty hyperdrive with an index.json file.

To Reproduce

1. Go to the Home page and scroll down to the "You have xxx legacy Drives which can be converted to Hyperdrive" section.
2. Click on a dat side "Convert" button.
3. Click "Convert" on the next page.
4. The resulting page only displays an index.json file.

Expected behavior
A page that displays all the files with the dat repository, or the option to save existing files before converting them.

Desktop (please complete the following information):

• OS: Linux Mint 19
• Version 1.0.0 prerelease 3

Sorry for (yet another) dat converter bug. I updated the stack and did some extensive testing, during which I ran into this and resolved it.
