(core) Fix renaming columns when iterating over Table.all in comprehension

Browse Source 
Summary:
Comprehensions iterating over `Table.all` like `[foo.bar for foo in Table.all]` led to an error when renaming the column `bar`. This diff fixes that so that renaming `bar` does the same thing as for a comprehension over `Table.lookupRecords()`. Note that `next(foo for foo in Table.all).bar` is still not supported, as the same is not supported for `Table.lookupRecords()` either.

Test Plan: Parametrised existing Python test to test the same thing for both `all` and `lookupRecords`
