[Bug] Crashes every time TextView grows if you don't declare textViewDidChangeHeight from the Delegate

[nuno-vieira]

If you don't define the textViewDidChangeHeight "optional" method from the delegate, it crashes. So i don't actually need that method from the delegate. So for now, i'm calling the method, but leave it empty.

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Vilger.MessageViewController textViewDidChangeHeight:height:]: unrecognized selector sent to instance 0x7fc978d23720'

Update: I thought that is was happing only in version 0.2.2, but on version 0.2.1, it does the same

[KennethTsang]

I was wrongly unwrapping the optional delegate when calling it. It has been fixed. Thanks!

By the way, the delegate method has changed since 0.2.2:
textViewDidChangeHeight(_ textView: GrowingTextView, height: CGFloat)

No problem! Nice library, congratulations! I'll help whenever i can, and i'll be using it for sure, it is really handy ;)
