Typo in a constructor property

**Description**

In the file ``search-results.js`` which is inside ``src/BookNavigator/search/search-results.js`` there is a typo. In the **IABookSearchResults** class, there is a property named ``renderSearchAllFields`` in the constructor, but the correct property name is ``renderSearchAllFiles`` according to the static properties definition.

**Evidence / Screenshot (if possible)**

**Expectation**

Instead of:
```js
this.renderSearchAllFields = false;
```
It should be:

```js
this.renderSearchAllFiles = false;
```
