Implement Test Methods For Admin Pricing

Similar to the other test methods in CustomGento_ConfigurableTierPrices_Test_Model_ObserverTest, there should be methods, which check the pricing in the admin area:

/**
 * @test
 * @loadFixture createProducts
 * @doNotIndexAll
 */
public function testProduct1AdminPricing()
{
    // TODO implement test
}

/**
 * @test
 * @loadFixture createProducts
 * @doNotIndexAll
 */
public function testProduct1AdminTierPricing()
{
    // TODO implement test
}
