[LANG-1544] MethodUtils.invokeMethod NullPointerException in case of null in args list (#680)

* LANG-1544:
- Null guards in place to handle one or more nulls specified as one of the parameters of the method to invoke.
- Check for an exact match of the actual parameter types against all of the methods on the class. This prevents picking an "upcasted" method (i.e. int specified but a method with a double is chosen).
- Throw an IllegalStateException with a helpful message if multiple candidate methods were found. This happens when multiple Methods had the same "distance" from the desired parameter types. Before this change the algorithm would just chose the first one.
- Tests for the above.
