[Kotlin] Package directive does not match file location & test cases do not see modifications in the file under test

## Describe the bug

### How it works for Java

The following java class

```java
package org.tests;

public class GeneratedMethodPublicInvokesPrivateTest {

@Test
public void methodPublicInvokesPrivateTest() {

}
}
```

is located in

`/private/var/folders/pm/<>/T/testSparkResults/test_gen_result_<>/org/tests/GeneratedMethodPublicInvokesPrivateTest.java`

And the IDEA see that the package name and the location (the suffix of the path) matches. So we can have the proper access to the package elements.

### How it works for Kotlin

The following kotlin class

```kotlin
package org.example

class GeneratedConstructorPrimaryNameOnlyTest {

@Test
fun constructorPrimaryNameOnlyTest() {

}
}
```

is located in

`/private/var/folders/pm/<>/T/testSparkResults/test_gen_result_<>/org/example/GeneratedConstructorPrimaryNameOnlyTest.kt`

But IDEA shows me the warning: **Package directive does not match the file location**. So we have the problem with access.

For example, we can not access, so the compilation for all tests of this class will fail.

```kotlin
internal class MyClass(private val name: String) {}
```
