Plugin Admin beta showing incorrect order of versions

[afragen]

In the beta Plugin Directory dashboard I see that a couple of my plugin active version stats are not in the correct order.

The most current version is on the left followed by other versions in ascending order to the right.

In 3794:

Plugin Directory: Only shift aggregated versions in active install graph.

Fixes #1897.
