Views can't be used as bindVars when constructing an AqlQuery

```js
const view = db.arangoSearchView("some-view");
const result = await db.query(aql`
  FOR d IN ${view}
  SEARCH PHRASE(d.key, "some value", "text_en")
  RETURN d
`);
```

The above throws `ArangoError: AQL: SEARCH condition used on non-view near 'RETURN d' at position 4:3 (while parsing)`. 

I can make this work by using `const view = db.collection("some-view");`, but that's a hack.
