Unnecessary reflection used for val properties that can be set via constructor #1190

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)
}
