Send NString to a reject function instead of NSException. React-Native 0.79

[KorotkovAlex]

In react-native 0.79 reject interface are changed. We should send NSString instead of NSException

I can confirm - reject on 0.79 bridgeless crashes the app if NSException is passed instead of NSString.
Changing to e.description has fixed it for me.

Also, API of reject has expected NSString for few years already so it means that the mapping layer has become stricter in 0.79 but merging it shouldn't cause any problems on older versions
