Streamline database access

An unsuccessfull attempt to get rid of the warning "connection treedb is
still in use..." by trying to delete all queries and setting mDb to
QSqlDatabase() in the destructor.

Strangely enough, the warning is only issued from inside QtCreator...
Maybe it's some kind of race.
