Expected Behavior

frostfs_node_blobovniza_tree_size_bytes metric must be positive.

Current Behavior

frostfs_node_blobovniza_tree_size_bytes metric can be negative.

Steps to Reproduce (for bugs)

Start xk6 test:

#!/bin/bash

echo "Generating preset..."
time /home/dstepanov/src/xk6-frostfs/scenarios/preset/preset_grpc.py \
--size 8 --containers 1 --out /home/dstepanov/src/xk6-frostfs/grpc_preset.json \
--endpoint s01.frostfs.devenv:8080 --preload_obj 0 --wallet /home/dstepanov/src/xk6-frostfs/scenarios/files/wallet.json \
--config empty_pass.yml --policy 'REP 1 CBF 1 SELECT 1 FROM *' --ignore-errors
echo "Preset generated"

echo "Starting grpc write test..."
./k6 run -e DURATION=300 -e WRITERS=20 -e READERS=0 -e DELETERS=0 -e WRITE_OBJ_SIZE=8 \
-e GRPC_ENDPOINTS=s01.frostfs.devenv:8080,s02.frostfs.devenv:8080,s03.frostfs.devenv:8080,s04.frostfs.devenv:8080 \
-e PREGEN_JSON=/home/dstepanov/src/xk6-frostfs/grpc_preset.json -e STREAM_TIMEOUT=30 -e SLEEP_READ=0.2 \
-e SLEEP_WRITE=0.2 /home/dstepanov/src/xk6-frostfs/scenarios/grpc.js
echo "grpc write test completed"

Also after reboot metric frostfs_node_blobovniza_tree_size_bytes resets. But i don't think it's correct.
