Fixes bug where reposted events had wrong root coordinates

Fixes bug where reposted events had wrong root coordinates

Reposting happens when a menu is running and you click outside the
menu. The code was not setting the root_location of the newly created
event, resulting in anyone attempting to use the root (such as the app
list) getting the wrong thing.
