iOS app crashes at launch on release mode

[brunobar79]

Fatal Exception: RCTFatalException: Unhandled JS Exception: t must be composed with AccountTrackerController.

May be related to #19 ?

@bitpshr not sure if this helps but I was able to get a full stack trace by using stack-beautifier and the source map:

Additionally I've tried this without success.

Not sure if you're using this on GABA....

The other theory is that it could be related to this

EDIT: Actually, the last one is my preferred theory! Check this out: https://github.com/MetaMask/gaba/blob/master/src/ComposableController.ts#L59

EDIT 2: Confirmed! We need to use class.name instead of class.constructor.name and we need to add a getter method on each controller that returns the name. I did that and it works!
