Caolán McNamara 582a73abd2 tdf#64711 pointer deleted out from under std::shared_ptr 
the "end" call will close the shell, which is deleted directly so the local shared_ptr remains
pointed to something which is already deleted.

So:
a) Have activate return true/false to indicate the failure and require the caller to call
'end' in response to failure.
b) A bunch of stuff in the call-stack expects the ViewShell not to get deleted while they are
calling it, so additionally launch that 'end' to happen in the next event loop.
