Fix T47754: Meshes glitch on cycling Viewport Shading mode with Linked Groups 

This is a regression since 4310128 which is cased by really bad logic:
there might be dependencies between dupli-objects, which means _if_ we
really want to ensure derived mesh on dupli creation we have to do it
before any matrix is overwritten.

I'm not sure if such derived mesh trick is really the only way to go
without major refactor, but seems simple fix for now will do it.
