Electron 37 + Electron devtools installer 4, redux devtool tab not appearing

Nobody has claimed this yet.

I have configured everything as it should be, install the extension on app-ready, before creating the window. I see the errors below and i see the global object for redux devtool on window object. But no tab in devtools appearing. Refreshing the app does not help. I see that a fix was merged adding the new extensions api but no release was cut? Not sure if that would help.

```

```

Start by reproducing the missing Redux DevTools tab with Electron 37, installing the extension at app-ready before creating the window. Inspect the reported extension-loading and renderer errors and the newer Electron extensions API; done means the tab appears in DevTools without the reported failure.
