Make QSqlQueryModel::query() return a reference to the const QSqlQuery 

Returning QSqlQuery instance by value does not make much sense,
because it cannot be copied correctly. Also, its copy constructor
and copy-assignment operators are deprecated from Qt 6.2.

[ChangeLog][Potentially Source-Incompatible Changes][QSqlQueryModel]
QSqlQueryModel::query() now returns a reference to the const QSqlQuery
object associated with the model.
