Top level vals are not re-initialized if their initializing methods are in another class and changed

Consider we have a Kotlin file:

`Val.kt:`
```kotlin
val greeting = getGreeting()
```

where `getGreeting()` in another file:

`Greeting.kt:`
```kotlin
fun getGreeting() = "Hello"
```

If we change `getGreeting()` body `val greeting` will remain the same.
