No results in Search All Kits when pressing enter in search box

[joliet]

Describe the bug The original design of this feature was that pressing enter with the search box select and no text in the field would generate a list of all kits in reverse chronological order, i.e. the most recently-created kits. This functionality is not working.

To Reproduce Steps to reproduce the behavior:

1. Go to the Admin Console
2. Click on Search All Kits
3. Put cursor in the search box with no text and press enter
4. No results are displayed

Expected behavior Expected to see a list of kits created in reverse chronological order (most recent first).

@joliet not sure the best way to test this, since test only has ~1,000 courses so we can't tell if there is a speed increase in page loading. It does show 50 pages of results instead of 100 or whatever it was before, so we know we are at least getting the 500 we are aiming for.

LGTM @noahhh . Ready for prod.
