AssembleModel unable to analyze Kotlin constructors with not nullable reference parameters #1336

Description

Right now we are unable to properly assemble models if there are not nullable reference parameters in constructor -- such models are instantiated through reflection right now.

To Reproduce

Launch action on class Sample from below:

data class Point(var x: Int, var y: Int)

class Sample(val y: Point) {
    fun test(): Int {
        if (y.x == 2)
            return -1
        return 0
    }
}

Expected behavior

Tests with assembled models are generated.

Actual behavior

Classes are instantiated through reflection

Visual proofs (screenshots, logs, images)

@Test
fun testKek1() {
    val s = (createInstance("nullability.Sample") as Sample)
    val point = (createInstance("nullability.Point") as Point)
    point.x = 2
    setField(s, "nullability.Sample", "y", point)
    
    val actual = kek(s)
    
    assertEquals(-1, actual)
}

Environment

Symbolic execution 100%.

Additional context

Seems like the problem is that Kotlin compiler adds to constructor of Sample instructions like INVOKESTATIC kotlin/jvm/internal/Intrinsics.checkNotNullParameter (Ljava/lang/Object;Ljava/lang/String;)V

This leads to incorrect behavior of isAppropriate and other methods in ConstructorAnalyzer
