Pass original exceptions to the JS

[kober32]

!!! Note, that this should be done after Cordova is merged into the develop branch. Cordova has brand new files which copied this issue...

On Android, we're catching exceptions and passing our own errors:

For example here:
https://github.com/wultra/react-native-powerauth-mobile-sdk/blob/develop/android/src/main/java/com/wultra/android/powerauth/reactnative/PowerAuthModule.java#L430

this line should be

promise.reject(Errors.EC_BIOMETRY_FAILED, "Biometry dialog failed", error);

This passes the error to the React Native layer.

Improve PowerAuthErrorException reporting

When PowerAuthErrorException is passed in the way mentioned above, the getPowerAuthErrorCode is lost - we should somehow include it in a way that will be reported in the JS code.
