In rare cases, a second contraption can pick up multiblocks too quickly and the "prevControllerInfo" ends up null, crashing the game/server. Fixes Creators-of-Create#6915 and Creators-of-Create#6925

Hi!
We run a public Create server (running Minecraft
1.20.1) and it started crashing pretty regularly after updating to0.5.1h. Did some digging and found it's the same issue as #6915, albiet with gantries rather than pistons.My understanding is: in rare cases, a second contraption can pick up multi-blocks too quickly and the
prevControllerInfoends up null, crashing the game/server. I suspect there might be a "better" solution of kinda "doing it right" to prevent thenullfrom appearing in the first place, but my knowledge of the Create codebase is limited and this at least stops the server from crashing from this.Fixes #6915 and #6925
