[display] completion on type name is missing .new

Similar to classes, `new` should appear in completion here, but only a regular static function like `foo()` does:


Which actually, now that I mention it, seems to be broken for classes too?


The class case used to work in 3.4.7, so that part is a regression, but it never worked for abstracts it seems.

```haxe
package cases;

class Issue7273 extends DisplayTestCase {
/**
class Main {
static function main() {
Main.{-1-}
Foo.{-2-}
}

public function new() {}
}

abstract Foo(Int) from Int {
public function new() this = 0;
}
**/
function test() {
eq(true, hasField(fields(pos(1)), "new", "Void -> Main", "method"));
eq(true, hasField(fields(pos(2)), "new", "Void -> Foo", "method"));
}
}
```
