Call track async

[ladanazita]

Fixes #17

All public API calls to the Taplytics SDK are dispatched synchronously:

#define dispatch_main_sync_safe(block)\
if ([NSThread isMainThread]) {\
    block();\
} else {\
    dispatch_sync(dispatch_get_main_queue(), block);\
}

This is causing deadlock issues with our analytics-ios SDK on key lifecycle events which must be handled synchronously. To resolve this, we will call the Taplytics SDK asynchronously.

This will presumably need it as well, right?

[ladanazita]

Yes good catch, will add

@VicV How does this look now with the requested changes? Thanks!

[VicV]

Hey @ladanazita, it works well for me, but I'm waiting for @bbernberg to confirm this works sometime next week.

[VicV]

@ladanazita looks like everything is working for the client. Good to go! 👍

Thanks for the quick response on this. Really appreciate it.

LGTM. DRY would be nice but not required atm.

[VicV]

Awesome. @ladanazita any idea when this will be in prod and good to go?

[ladanazita]

@VicV I apologize for the delay, I was out of office yesterday. I can ship this today.

@VicV this is on 1.1.2 now, thanks for the help!
