[UIApplication delegate] must be used from main thread only

[kamelj]

Hello can you please find other way for this line in RCTPayfort.m:

UIViewController *nav = (UIViewController*)[UIApplication sharedApplication].delegate.window.rootViewController;

Application crashed and display this message:

This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.

Thanks :)
