opening app from another window/link hangs the app

issue:
opening an app that uses torii from another window/link (with `target="_blank"`) causes the app to hang (waiting for `application.advanceReadiness`).. It mistakenly thinks the app is a popup since `window.opener` isn't `null` 

A possible sol'n is to also check whether `window.name !== ""` 
Because torii appears to name the window when it opens a popup, checking if a name doesn't exist could be a good way to indicate that the app isn't in a popup triggered by torii

you can see a repro just by adding `target="_blank"` to this this `href`:

@mixonic Facebook sets name on the popup (e.g. `_e_0rfm`) even if a name is provided from `window.open`
A slightly intrusive alternative:
- save main app's `window.name`, or set it if none exists then always return a rejected promise from `redirectHandler.run` when name matches main app's `window.name`
