State storage doesn't work with ioBroker and docker

[stfnhmplr]

Node-RED emits the necessary close event only if the process is killed with SIGINT. ioBroker and Docker using SIGTERM so the close event is not emitted by Node-RED.

There's already a PR to expand the signals: https://github.com/node-red/node-red/pull/2447

You can use the following workarounds until the PR get's merged:

• Use docker kill --signal=SIGINT nodered to stop Node-RED gracefully.
• Create a flow in nodered and use the exec-node to kill the nodered process with SIGINT

Fixed with Node-RED@1.1.0
