Issue Description:

import Foundation

class Foo {
    @objc var bar: Int = 1
    private init () {}
} 

let path = #keyPath(Foo.bar)

The `Foo.Bar` ref inside the keyPath will not be indexed:

It turns out that the true problem is that only properties are being resolved, which triggers a difference in components.count x resolvedComponents.count which is being seen as an error. You can see that it indexes correctly in #keyPath(myProp).

The approach used to solve this has fizzled due to changes in the compiler. I'm de-assigning it
