Allow Grouping to pass along proxy_set of element
Repaired an issue where the "ORDER BY" clause rendering a label name rather
than a complete expression, which is particularly important for SQL Server,
would fail to occur if the expression were enclosed in a parenthesized
grouping in some cases. This case has been added to test support.
Fixes: #5470
Change-Id: Ie0e27c39e5d53be78b32f7810f93d2d0536375e7
