write-cache mode still READ-ONLY when we changed shard mode to READ-WRITE

Related to #1905

Expected Behavior

If we change shard mode to READ-WRITE, then write-cache mode should be changed to READ-WRITE too.

Current Behavior

I changed shard mode to READ-WRITE, but write-cache mode kept in READ-ONLY.

Steps to Reproduce (for bugs)

1. Set shard mode to READ-WRITE:

root@az:/srv/neofs# sudo neofs-cli --endpoint 127.0.0.1:8091 -w /etc/neofs/storage/wallet.json control shards set-mode --all --mode read-write
Enter password >
Shard mode update request successfully sent.

2. Try to flush cache:

root@az:/srv/neofs# sudo neofs-cli --endpoint 127.0.0.1:8091 -w /etc/neofs/storage/wallet.json control shards flush-cache --id MnaJVa2bAqANyXabcajLWQ,KNqV3sT3nSFQKMan7w54QH
Enter password >
Write-cache has been flushed.

3. Actually write-cache still in READ-ONLY:
