Bugfix: UsePlayerUpdateJobs 2 - when player leaves occlusion group, clean up last visibility timestamps - fixed whitespacing after merging messing it up in one of the files This caused negative feedback loop. If EntityQueue doesn't send snapshot during network subscription change (because of OcclusionFrameCache), the ServerOcclusion should send it, but having an expired visibility timestamp meant it didn't send the snapshot (expired == previously visible, so snapshot already sent). Tests: on Craggy with UsePlayerUpdateJobs 2 flew 2 players outside of network range, then made 2nd player fly in a minicopter to the 1st - was visible. Repeated this flight test 5 times - all passed.
