Error with custom contextBridgeApiKey

[danikaze]

I found that defining a custom contextBridgeApiKey in the options different to "api" (and placing the bindings there), this error is always triggered...

In my setup, I was abstracting the i18n setup placing it in window.__i18n instead of the default window.api...
If I set it on api, it works.

Based on my investigation, I found that i18next works creating an instance of the backend first with default options (no options), and then it calls instance.init() here with the proper options.

As the backend constructor calls this.init() here but the options haven't been set yet, it checks for the existence of window.api.i18nextElectronBackend by default... which is never going to exist because it should be defined in the custom key (window.__i18n.i18nextElectronBackend in my case).

Just commenting the call to this.init() fixes the problem... but I don't know if this call is needed for any compatibility issue with older versions of i18next...
