SI-6925 use concrete type in applyOrElse's match's selector
Fix a regression introduced in 28483739c3:
PartialFunction synthesis was broken so that we'd get:
```
scala> def f[T](xs: Set[T]) = xs collect { case x => x }
f: [T](xs: Set[T])scala.collection.immutable.Set[_ <: T]
```
rather than
```
scala> def f[T](xs: Set[T]) = xs collect { case x => x }
f: [T](xs: Set[T])scala.collection.immutable.Set[T]
```
