sfx2: try to fix lifecycle of SfxOfficeDispatch

This can be created either from the global SfxApplication, or from a
SfxViewFrame.

Particularly in the latter case, the SfxDispatcher and SfxBindings
members are owned by SfxViewFrame, so in case that is destroyed, the
SfxOfficeDispatch must clear its pointers.

It looks like the member pointers are checked before access already
everywhere, so just listen at the SfxViewFrame.
