On some chromebooks the "images" tab does not appear when attempting to
insert an image, instead the desired image needs to be found via local
storage.
For some reason although the settings element could be found, clicking
on it did not have the desired effect, to solve this the element has
been found as a UiObject2 instead.
On Android N running under the instrumentation uiautomator appears to have
trouble retrieving the root node for the home screen of google slides. Therefore
we open the navigation drawer via a swipe which allows the node to be found again.
The latest version of uiautomator2 seems to have an issue with google slides not
being able to interact with any elements on the slide therefore we are using a
slightly older version which doesn't have this issue.
