Description

When the subquery operator was introduced it missed the case for handling the subquery inside an aggregation function.
This PR adds support for it.

As per the issue group_concat does not accept more than one argument when evaluated at vtgate. That is still unsupported and is not the cause of regression. The queries reported in the issue would work now.
