unable to return online state after maintenance

Unable to return back to online state after maintenance mode

Expected Behavior

Node should be able to successfully set online state after maintenance mode.

Current Behavior

Node still in MAINTENANCE state when set-status --status online has been sent.

Steps to Reproduce (for bugs)

1. turn on Maintenance Mode config:
   neofs-adm morph set-config MaintenanceModeAllowed=true -c configuration/config.yaml
2. Issue netmap snapshot to verify that the node is in online state:
   neofs-cli netmap snapshot -g -r node1.neofs:8080
3. Set MM:
   neofs-cli control set-status --status maintenance --endpoint localhost:8091 -w /etc/neofs/storage/wallet.json
4. Tick epoch:
   neofs-adm morph force-new-epoch -c configuration/config.yaml
5. Issue netmap snapshot one more time (node state is maintenance):
   neofs-cli netmap snapshot -g -r node1.neofs:8080
6. Set node to online state:
   neofs-cli control set-status --status online --endpoint localhost:8091 -w /etc/neofs/storage/wallet.json
7. Tick epoch:
   neofs-adm morph force-new-epoch -c configuration/config.yaml
8. Issue netmap to verify the status, where ONLINE status is expected:
   neofs-adm morph force-new-epoch -c configuration/config.yaml

Actual result:
Node 3: 0266719a2438f03480efa6f29e895baa90bcb5e0aa398fb1c77398c377307cdabc MAINTENANCE /dns4/node2.neofs/tcp/8080
