Static methods are not being passed to return type of scope

Actual behavior:

I'm adding a static method to a model and want to use it together with the scope method. Eg. ModelName.scope("scopeName").staticMethod() but TypeScript is showing an error Property 'staticMethod' does not exist on type 'ModelCtor<ModelName>'.

This is a regression from sequelize-typescript version 2.0.0-beta.0 where this worked fine.

Expected behavior:

The expected behaviour would be that the return type of the scope method contains the static method.

Steps to reproduce:

Add a static method to a model and try to use it together with scope.

Related code:

import { Column, Model, Scopes, Table } from "sequelize-typescript";

@Table
@Scopes(() => ({
	scopeName: {},
}))
export class ModelName extends Model
{
	@Column
	columnName: string;

	static staticMethod(): string
	{
		return "do something";
	}
}

// This works
ModelName.staticMethod();

// This does not work. `Property 'staticMethod' does not exist on type 'ModelCtor<ModelName>'.ts(2339)`
ModelName.scope("scopeName").staticMethod();

I think this code should be enough but im willing to create a SSCCE if thats necessary.
