Correctly reset bestMoveChanges for searches not using time management (e.g. analysis, fixed node game play etc), bestMoveChanges was not reset during search iterations. As LMR uses this quantity, search was somewhat weaker. Tested using fixed node playing games: ``` ./c-chess-cli -each nodes=10000 option.Hash=16 -engine cmd=../Stockfish/src/fix -engine cmd=../Stockfish/src/master -concurrency 6 -openings file=../books/UHO_XXL_+0.90_+1.19.epd -games 10000 Score of Stockfish Fix vs Stockfish Master: 3187 - 3028 - 3785 [0.508] 10000 ./c-chess-cli -each nodes=30000 option.Hash=16 -engine cmd=../Stockfish/src/fix -engine cmd=../Stockfish/src/master -concurrency 6 -openings file=../books/UHO_XXL_+0.90_+1.19.epd -games 10000 Score of Stockfish Fix vs Stockfish Master: 2946 - 2834 - 4220 [0.506] 10000 ``` closes https://github.com/official-stockfish/Stockfish/pull/3818 bench: 5061979
