Fixed contact not being found when mistakenly selecting search for
bots instead of contact.
Changed element used to determine when contact has been
selected from status indicator to search icon as with other other
contacts in view the element is never removed.
Now throws error if end call button is not found otherwise workload
could fail to start the call and incorrectly report overall success.
Since there has been an update to the skype app, there was now a
update prompt preventing test from running. Now checks for the
prompt on older versions of skype and dismisses it if present.
