Option "Full Project Name" has no effect on commit status messages

When posting a commit status (pending/success/fail) message to IRC, the "Full Project Name" option for the hook has no effect; the message is always posted as just:

`[reponame] [...]. The Travis CI build [...]`

I would expect the option to make that, instead:

`[orgname/reponame] [...]. The Travis CI build [...]`

... like it does for every other message.
