Moodle is misreporting 'your moodle code is up to date'

1. I have one outdated contrib plugin (repository_skydrive - you can test this by downloading and downgrading version number manually).
2. I got to admin page and check for updates
3. moodle says 'Your code is up to date'
4. If I go to the plugins page it says there is one contrib update available, but thats not easily visible

Expected result
---------------
Moodle says 'Your Moodle code is up to date, there is one plugin update avaialble' (or something like that
