[PATCH setup, revised 2/2] Avoid clobbering installed.db when no setup.ini is found

[Ken Brown]

If no setup.ini is found, do_ini_thread is never called.  But we need
to ensure that packagedb::read is called, or else installed.db gets
emptied.  Move the calls to packagedb::read and other packagedb
functions from do_ini_thread to ChooserPage::OnInit.
