Refresh button should load using accessed URL not typed URL

[RangerMauve]

I think there's two ways we can approach this:

• Spit the refresh/go button into two buttons (this is what most browsers do)
• When you de-focus the omni-box, it should revert to whatever the current URL is
• Something else

I feel like the defocus could be a good solution.
One would need to have a go with it first and see if it feels odd/bad though.

I think we can reuse the custom event from #139. Currently the event is only fired when we press the ESC-button, but if we can make it fire on focusing the BrowserView/WebContents I think we will get the behaviour we want.
May require some workarounds since there's no native support for focus events of BrowserView/WebContents in electron yet: electron/electron#25873

I think the UX after @jolindroth 's fix in #139 makes this usable. Basically, after we navigate away the URL bar gets reset so you can reload normally again. 🎉
