Expected value is not created in Spring tests

[EgorkaKulikov]

To Reproduce

All mentioned classes and methods are taken from this project https://github.com/spring-projects/spring-petclinic

Generate tests for method Pet.getType

Expected behavior

Compilable tests are generated.

Actual behavior

Generated test looks as follows:

	@Test
	public void testGetType1() throws Exception {
		PetType petType = ((PetType) createInstance("org.springframework.samples.petclinic.owner.PetType"));

		PetType actual = pet.getType();

		// java.util.LinkedHashSet is iterable or Map, use outer deep equals to iterate over
		assertTrue(deepEquals(linkedHashSet, actual));
	}

Variable linkedHashSet was never declared.
It is not obvious why HashSets are used.

Does not reproduce after #2091 merge

Test looks as follows:

	@Test
	@DisplayName("getType: -> return this.type")
	public void testGetType_ReturnThisType() throws Exception {
		Pet pet = ((Pet) createInstance("org.springframework.samples.petclinic.owner.Pet"));
		PetType petType = ((PetType) createInstance("org.springframework.samples.petclinic.owner.PetType"));
		setField(pet, "org.springframework.samples.petclinic.owner.Pet", "type", petType);

		PetType actual = pet.getType();

		PetType expected = new PetType();
		String actualName = ((String) getFieldValue(actual, "org.springframework.samples.petclinic.model.NamedEntity", "name"));
		assertNull(actualName);

		Integer actualId = ((Integer) getFieldValue(actual, "org.springframework.samples.petclinic.model.BaseEntity", "id"));
		assertNull(actualId);
