FIX: Ensure first post is loaded before trying to bookmark topic (#9382) 

Load first post if not loaded when trying to bookmark topic

* if the first post was not loaded we could not bookmark it because
  now we call the toggleBookmarkReminder function on an actual post
  to open the modal window
* add a firstPost function to the topic model to get the first post
  from the stream if it is loaded and if not do a GET request to load
  it
* use the firstPost promise when bookmarking topic
