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.
In order to workaround an bug in applaunch running on android N, all of the
workloads have been updated to the latest gradle build system, the timeout in
the baseclass has been changed from a TimeUnit to a regualr long and a
duplicately declared parameter bundle has been removed.
