Can't inject ManagedExecutor since quarkus 1.6.0
**Describe the bug**
I'm trying to inject a ManagedExecutor (using Kotlin and injecting into `@Singleton` bean that extends `MutinyExampleServiceGrpc.ExampleServiceImplBase` if that matters) and get 
```
Parameter specified as non-null is null: method com.example.Example.<init>, parameter managedExecutor"
```
I tried both constructor injection as well as field injection via `lateinit var`

**Expected behavior**
ManagedExecutor is injected

**Actual behavior**
ManagedExecutor is not injected to my bean (both 1.6.0.Final and 1.6.1.Final)
But it's injected successfully if I change the version to 1.5.2.Final
