Attempt fix to RATSNEST crash 

We call 'RecalculateRatsnest' in multiple locations, this will
invalidate various pointers needed by VIEW::Redraw().  When this is
called through the normal connectivity routines, we have the mutex
locked to prevent conflict but we've added more locations that update
just the Ratsnest.  The std::adopt_lock should take over the existing
lock when needed
