/// The RecentTemplates class uses the RecentFileStorage class. In the

/// and may finish whilst the unit test is adding a new template. This task
/// delay can cause the cached in-memory list in the RecentFileStorage to be
/// cleared. This causes the test to fail since it will run before the
/// in-memory list can be updated when the RecentFileStorage class saves the
/// file to disk. This saving to file is delayed by a second. So we retry
/// getting the templates from the RecentTemplates until a timeout occurs.
/// Most of the time the RecentTemplates.GetTemplates method works first
/// time and returns the expected templates.
