GitHub Importer - Automatically refresh import status

Problem

When importing repositories from GitHub, the Status field does not automatically refresh. This leaves the user confused about whether their imports were successful and wondering if it's safe to refresh the page to see if the status gets updated, or whether that refresh might end up interrupting the import.

The entire interaction can be seen in this video.

Proposed solution

The import statuses should update in (near) real-time.

Further considerations

Quirky status updates can also be seen in this video, starting at 6:28. Clicking two individual [Import] buttons causes the Status fields to update incorrectly. It is expected that this issue will correct this behavior, as well. Otherwise, a new issue should be created.
