Fix #1820: condition of whether generates outer
Previously, we don't generate `outer` for the anonymous class `new Inner2 {}`.
This is incorrect, as `Inner2 {}` extends `A.Inner`, which requires an outer.
trait A {
val a = "a"
trait Inner {
def f = println(a)
def h = 3
}
}
trait B extends A {
trait Inner2 extends Inner
new Inner2 {}
}
