Keep Dialogs which report process around.

Since 5.8-245-g3e43585fa, a response hides the dialog Window
in ArdourDialog::on_response (to prevent dialogs windows staying
around unresponsively while Ardour does background work).
This logic does not apply to Dialog Windows which implement
ProgressReporter or support dialog responses other than OK, Close.
