Don't forget to dispose the component here.

Otherwise, none of the associated SfxViewFrame, SfxBaseController,
SfxObjectShell, SfxMedium etc would get destroyed which would ultimately
lead to the .~lock.foo file not being deleted upon exit.

But for this to work, the client code has to make sure that its
LibreOfficeDocument instance gets destroyed when it finishes its thing.
