This prevents a null exception that could otherwise occur during code
completion. I think that this only impacts internal users.
It's not ideal. As you can see from the tests OpType is deciding that
we should be suggesting type names in places where they can't exist,
but I think that's a theoretic issue because I believe that the code
completion code won't access the OpType in these situations.
If I'm wrong, then the failure mode will be to suggest type names
that shouldn't be suggested in a couple of situations. If users do
notice this behavior it should be relatively easy to tighted up the
computation to only suggest the valid completions.
