evgen@moonbone.local 0c9f941bb2 Fixed bug#20825: rollup puts non-equal values together ...

Fix for bug 7894 replaces a field(s) in a non-aggregate function with a item
reference if such a field was specified in the GROUP BY clause in order to
get a correct result.
When ROLLUP is involved this lead to a wrong result due to value of a such
field is got through a copy function and copying happens after the function
evaluation.
Such replacement isn't needed if grouping is also done by such a function.

The change_group_ref() function now isn't called for a function present in
the group list.
