Abstract static interface methods support is incomplete

[lostmsu]

The current implementation happens to work for generic math via System.Numerics.INumberBase<T> because for all primitive type T happens to be of the same type as the type itself (e.g. for Int32: T == Int32).

In general case this is not true. And the Disassembler.ExtractMethodBody fails on method.DeclaringType.GetGenericArguments()[0]; line with IndexOutOfRangeException because the interface that contains abstract static method does not even have to be generic. As far as I see, at this point the information about the type, that implements that static abstract method is not available at all.
