    Fix "Edit Comment" Dialog title when launched from Events Directory page
    
    As described in #4930, editing an event comment from the Events Directory page
    currently brings up a dialog titled "Edit photo/video comment".
    
    This MR passes is_event=true to the corresponding call to the EditCommentDialog
    constructor, changing the dialog's title to "Edit event comment" as expected.
    
    Fixes #4930
