Reference checking this {@link Unwrappable} to another {@link Unwrappable}, ignoring wrappers.
Two {@link Unwrappable} are considered equal ignoring wrappers if they are of the same object reference
after {@link #unwrapAll()}.
@param other The {@link Unwrappable} to compare this {@link Unwrappable} against
@return true if the argument is not {@code null}, and it represents a same object reference after
        {@code unwrapAll()}, false otherwise.
