Title:
  Autopilot emulator can loop infinitely while searching for tab

Status in Ubuntu UI Toolkit:
  Fix Released
Status in “ubuntu-ui-toolkit” package in Ubuntu:
  Fix Released

Bug description:
  The autopilot emulator need sto make sure we don't have open ended
  loops in tab switching.

      def switch_to_tab_by_index(self, index):
          """Open a tab.

          :parameter index: The index of the tab to open.
          :return: The newly opened tab.

          """
          tabs = self.get_tabs()
          if index >= tabs.get_number_of_tabs():
              raise IndexError('Tab index out of range.')
          current_tab = tabs.get_current_tab()
          while not tabs.selectedTabIndex == index:
              current_tab = self.switch_to_next_tab()
          return current_tab

  Let's add a controlled exit once we've checked every tab and fail to
  exit the loop. I've NO idea why or how we could not find the tabIndex,
  but it's happening in the weather app smoke tests at present, and in
  general this has potential to loop.
