turn off deduping for col expressions
Fixed ORM issue where column expressions passed to ``query()`` or
ORM-enabled ``select()`` would be deduplicated on the identity of the
object, such as a phrase like ``select(A.id, null(), null())`` would
produce only one "NULL" expression, which previously was not the case in
1.3. However, the change also allows for ORM expressions to render as given
as well, such as ``select(A.data, A.data)`` will produce a result row with
two columns.
Fixes: #6979
