    appveyor: Re-enable non-tag builds
    
    Appveyor has some issues building tags if the tag isn't actually the
    most recent commit on that branch. In our release workflow this is
    theoretically fine, but because we're mirroring the repos across to
    Github, in reality I've always pushed the post-release version bump
    commit before the tag actually gets mirrored.
