Unnecessary reflection used for val properties that can be set via constructor

[volivan239]

Description

If constructor has a val property, codegen doesn't use this constructor but instead instantiates class via reflection although it can normally be done without it.

To Reproduce

Launch action on the following class:

class CustomClass(val x: Int) {
 fun f(): Int {
 return x
 }
}

Expected behavior

Correct tests are generated, reflection is not used at all.

Actual behavior

Generated tests contain reflection usage.

Visual proofs (screenshots, logs, images)

One of the generated tests:

@Test
fun testF1() {
 val customClass = (createInstance("CustomClass") as CustomClass)
 setField(customClass, "CustomClass", "x", -255)
 
 val actual = customClass.f()
 
 assertEquals(-255, actual)
}
