RootPath is not used for findBar results

Steps to reproduce

1. Create an app and set a rootPath in the browser subapp datasource:

subApps:
  browser:
    datasource:
     rootPath: /myRootPath/

1. Add an Item within the root path
2. Close the app
3. Search for the item in the find-bar
4. Click on the result
5. The right app is open, but the result is not preselected

Expected results

The url contains the full path of the node, to highlight/select it correctly:
http://localhost:8080/dev/.magnolia/admincentral#app:myApp:browser;/myRootPath/myItem:edit

Actual results

The url does not contain the rootPath, and therefore the node path is not absolute and the item is not preselected/highlighted:
http://localhost:8080/dev/.magnolia/admincentral#app:myApp:browser;myItem:edit
