Unused imports

[Romick2005]

Hi @zxcpoiu, great job on the voip push notifications!
I have a small question. While I was inspecting your code I noticed that there are unused imports:
#import <React/RCTConvert.h>
#import <React/RCTUtils>
I am new to Objective-C so I cannot be 100% sure about this. So if they are really unneeded, should I fire a PR for that or you will just adjust that in next release?

I was refer to some boilerplate somewhere, if you removed the two import and everything are build and work as usual, it's welcome to fire a PR then 👍
