Confusing UI when importing from GitHub

Problem

When importing a project from GitHub, the [Import X repositories] button is very confusing.

The entire interaction can be seen in this video.

Steps to reproduce

1. On the GitHub import page that shows the repositories available for import, initiate one import. (green)
2. The [Import X repositories] button is grayed out, shows a spinner and the text inside changes to [Import Y repositories], reflecting the remaining count. (red)

This is unexpected and the active spinner inside the button gives the impression that it is doing something (importing 3 repositories, even though I only initiated 1?!?).

Proposed solution

The spinner in the [Import X repositories] should only be displayed when the user presses that button. In cases where individual import buttons are pressed, this button should remain grayed out.
