Auto update toggle on/off on failed feed modal

When a feed fails to load (large feed), you get the feed-failure modal.

When the feed-failure modal is shown the auto update control is toggled off (it should just be disabled). We do not want auto update to run while loadEventsSuccessPending or loadEventsFailure, but we also want to maintain the user's selection for auto update.

So, it should work like this:

• when loadEventsSuccessPending and loadEventsFailure the feed should not auto update until a new feed is selected
• auto update should not be changed
• the auto update setting should be disabled when a search is selected
