fix: DH-20500: Links without operators not working

[mattrunyon]

This check was added here and caused links created before we had an operator to not function. We have logic that defaults to equals effectively if the operator does not exist.

We may want to clean that up and add a default in the future to migrate any old links, but this is the simple fix for now and there's not much harm in it
