(core) Update attributes of Table.all when column is renamed

Summary: Adds an InferenceTip which treats `Table.all` similarly to `Table.lookupRecords(...)`, so that `Table.all.foo` is changed to `Table.all.bar` when the column `foo` is renamed to `bar`.

Test Plan: Extended test for the `lookupRecords` case.
