Title: Fix missing parens in calls to extracted methods with empty parameter lists

This PR addresses an issue reported in scala-ide/scala-ide#686 by @huitseeker:

```scala
class ExtractorTesting {

val major: Int = 1
val minor: Int = 2
val patch: Int = 3

major * 100000 + minor * 10000 + patch * 100

}
```

Should give me

```scala
class ExtractorTesting {

val major: Int = 1
val minor: Int = 2
val patch: Int = 3

extracted()

def extracted() = {
major * 100000 + minor * 10000 + patch * 100
}
}
```
