Change Refresh to not return an error
Refresh is one of those functions that shouldn't require error handling (similar to triggering a redraw of the UI, see #3887). As far as I see, the only reason why Refresh can currently return an error is that the Then function returns one. The actual refresh errors, e.g. from the git calls that are made to fetch data, are already logged and swallowed. Most of the Then functions do only UI stuff such as selecting a list item, and always return nil; there's only one that can return an error (updating the rebase todo file in LocalCommitsController.startInteractiveRebaseWithEdit); it's not a critical error if this fails, it is only used for setting rebase todo items to "edit" when you start an interactive rebase by pressing 'e' on a range selection of commits. We simply log this error instead of returning it.
