Completion handler is not called

[apfritts]

The provided completionHandler is being saved to the remoteNotificationCallbacks dictionary, but the native onFinishRemoteNotification:(NSString *)notificationId fetchResult:(UIBackgroundFetchResult)result function didn't actually lookup and call the completion handler.

I believe this fixes that bug and addresses #216 #244 #297 as well.

Looks great. I think the example project needs to be updated as well 👍🏼

[apfritts]

@leethree I updated the example project and rebased my PR. I still need to re-confirm that this is functioning properly before it gets merged since there seem to have been quite a few other commits since I opened this.

This is still an issue -- any updates on when this can get reviewed and merged?

LGTM

This merged work looks like an approximate revert of 1506ddf / #241, which was marked as addressing #163. Do we expect #163 not to be re-introduced?

@chrisbobbe @Naturalclar
I'm experiencing this issue #163 after bumping to 1.11.0. (previously 1.10.1)
I think, in my project, there's some duplicated handling of FCM event.
(I'm using a couple of libraries that deal with FCM events.)

I think we need to be clear about the responsibilities of this library.
