Child Widget extends another non-abstract parent Widget would throw NoSuchMethodException if child using parent method

Description

Child Widget extends another non-abstract parent Widget would throw NoSuchMethodException if child using parent method

Details

For example:
I only tried in OverrideWidget scenario. Below example could reproduce the issue:

There is an abstract Widget named AbstractWidget, I implemented two widgets AndroidParentWidget and IOSParentWidget to extends AbstractWidget.

Then I implemented another widget named AndroidChildWidget extends AndroidParentWidget. in AndroidChildWidget, I only added one more method. Other existing methods such like parentMethod() in AndroidChildWidget just being extended directly without override.

When invoking AndroidChildWidget.parentMethod() in test code, it would throw NoSuchMethodException.

I found a workaround: override parentMethod in AndroidChildWidget explicitly with super.parentMethod(). it would work

Sometimes I would got NoSuchMethodException in OverrideWidget scenario with plain standard usage.
After applying #418 (comment),
the exception chagned to IllegalArgumentException: Constructor not found: ( it seems more accurate)

java.lang.IllegalArgumentException: Constructor not found

It seems that the enhancer trying to new an instance of the abstract widget class caused failure.

@TikhomirovSergey any suggestion? The OverrideWidget implementation is too complex, I debugged a long time and found nothing.

If there had been any problem then it seems it was fixed there #392. I can't find a way to reproduce it. Please provide the code sample as a gist and reapen this one.
