This avoids using -1 as the task's display ID and use the default
display ID instead.
In `TaskbarRecentAppsController#reloadRecentTasksIfNeeded()`, it filters
the first DesktopTask instance from allRecentsTask. Previously, the list
is built as nested lists with the same deskId = -1. This causes the
taskbar to show the running/minimized desktop apps incorrectly.
