tmf: Change TmfEventsTable to not use Display.getCursorLocation

This makes CallsiteEventsInTableTest (SWTBot) more stable because
Display.getCursorLocation is getting the cursor location straight
from the windowing system and therefore does not work properly with
SWTBot. Instead, we can use the last position of the MenuDetect
event to know the location.

Also update the targets sequence numbers to pick up required fix
from SWTBot, see SWTBot bug 474747.
