Aggregation tests have switches with impossible branches #88745
Description
The following aggregation tests all contain switch statements with branches that will never execute. The tests use a between(x, y) switch expression, but there are case values that are outside the randomised range. We need to fix these before #88739 can be merged. By "fix", I mean either remove the spurious cases, or if we actually want them, then extend the randomized range.
