Fix incorrect frame deletion, only noticeable when eeschema is run in stand alone mode.
After selecting a footprint using the footprint viewer, the application cannot be closed.
Reason:
the footprint viewer ctor creates an instance (not shown) of a FRAME_PCB.
Unfortunately, this pcb frame was not deleted by Eeschema, in stand alone mode,
preventing the application to be closed because a frame was still active after closing the schematic editor frame.
Now the footprint viewer ctor delete this instance after use, if it was not previously existing.
