Access to tokenManager class

[jcao02]

[REQUIRED] Describe your environment

• Operating System version: ubuntu 14.04
• Firebase SDK version: 4.1.3
• Firebase Product: messaging

[REQUIRED] Describe the problem

I want to implement a service to manage the token using your sdk. For that, I want to be able to check if there's a token stored locally, unfortunately you only provide getToken which doesn't tell whether it got the token from FCM or from the local DB.

Searching inside your code, I noticed you have a token manager class which is private. Perhaps you could make it public or at least a couple of its methods.

Steps to reproduce:

Just check the interfaces

Relevant Code:

I'd like to be able to do something like this:

const token = messaging.getSavedToken();
if (!!token) { /* Do something */ }

// OR

const hasToken = messaging.hasSavedToken();
if (hasToken) { /* Do something */ }

What is the use case for getSavedToken() ?
