78f2fe8d5e C++: Fix join in 'argumentOf'. 
Before:
```
[2023-06-28 09:29:51] Evaluated non-recursive predicate DataFlowImplCommon#59e7a193::Cached::argumentNode#3#fff@8606bd35 in 1945ms (size: 1366058).
Evaluated relational algebra for predicate DataFlowImplCommon#59e7a193::Cached::argumentNode#3#fff@8606bd35 with tuple counts:
