Software center reviews can be voted infinite times

Confirming this issue as it is part of the spec but we have not yet implemented it as part of the submit usefulness feature.

Linked branch has a fix for this issue, but will only work for usefulness votes submitted AFTER this fix has been released.

This is an interim solution which will work until the server can support keeping track of who has voted (at which point we can also implement the UNDO functionality in the spec)

This bug was fixed in the package software-center - 3.1.23.2
