Fix running Compose application after ProGuard optimizations. (#706)

Fixes JetBrains/compose-multiplatform#3387

It is probably a bug of proguard, it can't properly inline variables in some cases.

## Test
export COMPOSE_CUSTOM_VERSION=46436.333.66
./gradlew :mpp:publishComposeJbToMavenLocal -Pcompose.platforms=jvm

Open https://github.com/JetBrains/compose-multiplatform-desktop-template

Insert this code:
```
import androidx.compose.animation.AnimatedVisibility
import androidx.compose.material.Text
import androidx.compose.ui.window.singleWindowApplication

fun main() {
    singleWindowApplication {
        AnimatedVisibility(true) {
            Text("SDg")
        }
    }
}
```
./gradlew runReleaseDistributable

It runs without crashes after the fix. Before the fix it crashes with the crash:
```
Exception in thread "main" java.lang.VerifyError: Instruction type does not match stack map
