support for TypedQuery jpaql/hql "scalar" queries

Description

I'm getting a
java.lang.IllegalArgumentException: Cannot create TypedQuery for query with more than one return

with a query that returns a View object.

AbstractEntityManager:279, detects as many returns type as there is parameters in the View object, instead of one single result type, the View Object itself.

QueryString example that fails with public <T> TypedQuery<T> createQuery(String jpaqlString, Class<T> resultClass):

"select new WorkContractDto(wc.workContractStartDate, wc.workContractEndDate, wc.workContractEmployeeLastName, wc.workContractSendingStatus) from WorkContract wc where wc.workContractEmployeeLastName = ?1"

but i see your posts for named queries in https://hibernate.onjira.com/browse/HHH-6695.

The issue using a named query is covered by HHH-6304.

if ( namedQuery.getReturnTypes().length != 1 ) {
throw new IllegalArgumentException( "Cannot create TypedQuery for query with more than one return" );
}
