BUG/MINOR: stats: fix inversion of failed header rewrites and other statuses

The tooltip in the HTML stats page was damaged by commit 1b0f85e47 ("MINOR:
stats: also report the failed header rewrites warnings on the stats page"),
due to the header rewrites counter being inserted at the wrong place and
taking the place of the other statuses.

This is only for 1.9, no backport is needed.
