Fix qWarnings() at startup and shutdown

Fix unexpected NULL receiver on startup: Turns out this warning is
issued when calling deleteLater on a NULL object. This happened in
SheMov::createOpenWith*.

The "database is still in use" warning was a bit harder to track down.
First of all, the destructors weren't called since Qt::WA_DeleteOnClose
wasn't set for SheMov, so Qt would simply exit and let the OS do the
cleanup without calling the destructors.

Then there were several orphan widgets/objects without a parent, so
their destructor would never be called.
