Improve exception safety with smart pointers

Would you like to wrap any pointer data members with the class template “std::unique_ptr”?

Update candidates:

• CAccountViewTest
• CCacheDBManager
• CContractDBTest

Thanks for reporting. We will be doing this kind of nice-to-have housecleaning in the 4.0 release.

cheers, Richard
