Initializing fields of recovered records caused running &default expression of fields just so that they are re-assigned in the next step with the recovered fields. The second test case still shows that the loop var is initialized as well even though that's not needed. Add tests for iterating over records with &default attributes for both, tables and vectors. Fixes #3267

# @TEST-DOC: Iterating over tables with record keys would previously evaluate &default during each iteration. Ensure this isn't happening. Regression test for #3267.
