Fix possible refering to unallocated memory by using QSharedPointer #66

Hi @HamedMasafi With a bit more complex (tables with several foreign keys) model I got segfaults because the lastRow pointed to a data of a shared pointer which got deallocated in the previous loop. Using a shared pointer on the lastRow field solves this issue.
