Device "Editor Access" Enable/disable not working correctly

[Steve-Mcl]

Current Behavior

Clicking "Editor Access" Enable button appears to enable the tunnel momentarily then falls back to disabled state

Additonaly, actually opening the Node-RED editor for the device (proving the tunnel is indeed is working) the developer mode page still shows the tunnel disabled - meaning we users can no longer manually close the tunnel.

Expected Behavior

Fix operation of button

We may wish to revise the whole situation in light of recent changes to how the tunnel is initiated and the ongoing auto reconnect work in FlowFuse/device-agent#222

Steps To Reproduce

click "Editor Access" button on the Developer Mode tab of a device.

Environment

• FlowFuse version: 2.1
