tdf#162696 qt weld: Do GUI things in main thread

, the destruction of `QtInstanceDialog::m_pDialog` (that
previously implicitly happened due to it being a
`std::unique_ptr`) also needs to happen in the main
thread.

Otherwise, it triggers this assert with a debug Qt build
for the tdf#162696 of installing an extension via drag'n'drop
into the start center:

ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread QThread(0x7f4b14003390). Receiver 'QDialog(0x562e6ba77450)' was created in thread QThread(0x562e69709f60, name = "Qt mainThread")", file /home/michi/development/git/qt5/qtbase/src/corelib/kernel/qcoreapplication.cpp, line 551
