Cars and rockets built before builds were recorded have no subkey and no
ugc_modular_build row, so the client has no blueprint id to ask for their
icon with. When a character loads, such an item (a ModularBuildComponent
createdLOT with assemblyPartLOTs but no subkey) gets what a new build
gets: a persistent id as its subkey and a ugc_modular_build row with its
modules and owner. The next save keeps the subkey; nothing is dropped.

ModularBuildFinish hardcoded the item a finished build becomes (6416 for 3
parts, 8092 for 7) and the car chassis part (8129) that the every-part-
swapped check skips. They now come from ModularBuildComponent: createdLOT,
<numberOfParts> and the <ExamplePartLOT> of the <rootPart> module (new
CDModularBuildComponentTable). Same results with the 1.10.64 cdclient;
tests cover the xml parsing and the lookup.
