Message:

Fix notice errors when an activity is generated for a post having no title.

Post types activities are using dynamic action strings when the activity is displayed in the stream and when the activity is saved into the database. In this particular case, once the post is published, we are "faking" an activity object to which we add two extra properties : the post_title and the post_url. To avoid switching blogs too many times, we are saving the post title into an activity meta. To know if we must build the action string for insert or display, we are checking the post_title property of the activity object. When a post is published without a title, the empty() check was not right. Changing for an isset() check prevents the notice errors.
