From looking at the code of assignFactoryCommandDroid:
-On client 0 (host), assignFactoryCommandDroid() was called with psFact->psCommander ≠ NULL.
+On client 4, either assignFactoryCommandDroid() was not called, or psFact->psCommander = NULL.

And from here on, everything probably got completely messed up, due to the original difference.

Fix commander-related desynch and crash.

Would probably desynch on building anything in a factory assigned to a commander.

Would crash if assigning a VTOL factory to a commander, building a transport, and trying to unload the transport
(which would appear to contain everything assigned to said commander).

The .psCommander and .psAssemblyPoint should probably be syncronised at some point, but for now, are done like
this.

Fixes #1924, #3296 and #3676.
