Treat 'Basic / Final' (e.g.) as 'Basic', not 'Final'
When a result row lists the milestone as 'Basic / Final' (for
e.g.), currently we wind up treating it as 'Final' (we take the
*last* milestone name we encounter in the string). In practice
it's usually going to be a bit more correct to take the *first*
milestone name we encounter. So, let's do that.
