When navigating from a promise I get frame-common.js:173:127: JS ERROR Error: Corrupted navigation stack

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• CLI: 2.0
• Cross-platform modules: 2.0
• Runtime(s): 2.0
• Plugin(s): nativescript-auth0

Please tell us how to recreate the issue in as much detail as possible.

Clone the plugin repo https://github.com/sitefinitysteve/nativescript-auth0, run the iOS demo...
When it loads you should see the lock screen, login, then when the promise returns you should be navigated to the homepage (this was fine in 1.7). 2.0 though throws this and crashes the app.
