tdf#121143: don't send OnCloseApp twice; properly cleanup AppBasicManager
The OnCloseApp event is being sent twice: first time in
SfxTerminateListener_Impl::notifyTermination (in Desktop::terminate),
and the second time in Desktop::doShutdown. The second event happens
after application's Basic manager already was destroyed in
SfxApplication::Deinitialize. The Basic provider, which holds a pointer
to the manager, doesn't properly cleanup upon the manager's destruction,
thus trying to use it after free.
This removes the second (duplicate) generated OnCloseApp event, and
makes BasicProviderImpl inherit from SfxListener to allow receiving the
manager's SfxHintId::Dying notification.
