[Tests] Re-enable skipped legacy test

[smnandre]

In MakeEntityTest, we can read the following lines

maker-bundle/tests/Maker/MakeEntityTest.php

Lines 122 to 125 in 0624f13

	yield 'it_creates_a_new_class_and_api_resource' => [$this->createMakeEntityTest()
	// @legacy - re-enable test when https://github.com/symfony/recipes/pull/1339 is merged
	->skipTest('Waiting for https://github.com/symfony/recipes/pull/1339')
	->addExtraDependencies('api')

Well, it has been merged :)
