fix(type-factories): Correct types on instanceOf type factory

[JoseLion]

This PR corrects the types of the TypeFactories.instanceOf(..) helper. The issue was that the assertion factory was creating an assertion for the constructor instead of the instance. Using the alias Constructor<T> instead resolves the issue as the assertion factory will create an instance for T instead.

Example:

class Car {

  private model: string;

  constructor(model: string) {
    this.mode = model;
  }
}

expect(value)
  .asType(TypeFactories.instanceOf(Car))
  .toBeEqual(new Car("Porsche 911"));
