Avoid saving to disk and generating thumbnails for in memory database

Specify correct values for default arguments as suggested by Dragan Toroman


"You should also correct the calls to database.insert() to reflect the needed use.
For instance, in ctkDICOMQuery, the call to database.insert() is missing "false, false"
(causing some side-efects, like trying to generate thumbnails for non-existent images)"
