Start render module CL_MeshEntities immediately prior to Models
Fixes https://gitlab.com/xonotic/darkplaces/-/issues/366
Starting CL_MeshEntities any later can cause the bug during r_restart.
ca03733fba98709e25d9a02882ac947f4144af6a effectively added dependency
of the Models module on the CL_MeshEntities module,
at least in certain situations where starting the Models module
results in calls to Draw_CachePic() and DrawQ_*()
which trigger the bug when they call Mod_Mesh_GetTexture().
