SimpleDeadCode - removal of unused parameters broken.


```workspace/akka/akka-testkit/src/main/scala/akka/testkit/ExplicitlyTriggeredScheduler.scala:34:36```

When removing unused parameters - code does not handle seperators correctly
```
class ExplicitlyTriggeredScheduler(@unused config: Config, log: LoggingAdapter, @unused tf: ThreadFactory)
```
becomes
```
class ExplicitlyTriggeredScheduler(, log: LoggingAdapter,)
```
