[a11y] Evolution doesn't send "object:text-selection:changed" events when text is selected or unselected.

In order for Orca to be able to tell when text has been selected or unselected, it relies on receiving "object:text-selection:changed" accessibility events. Unfortunately, Evolution is not sending any.
Looks like there is already an Evolution bug on this. Closing as a duplicate. *** This bug has been marked as a duplicate of 347347 ***
