* Fix mantis 757.

* DelinkFromGroup was removing the parts from the delinked group, which later upset the update thread when it tried to do a queued update for that object
* Temporary fix is to stop deleting the parts, though it would be good later to stop sending out the now spurious updates
* This fix actually reveals another bug, where rapid linking and delinking will cause the non root prims to disappear (though they're actually still there if you relog).  This is the next bug to tackle.
