Similar to dashboard tasklists, the search results should show the tags associated with a maniphest task.
This way, if phabricator is being used in multiple projects, two tasks without the project name in the taskname can be differentiated.
For example I might have a "add search bar" tasks for project 1, and another task "Add search bar" for project 2. Showing the tags lets me know which projects the task is for in the search result. I don't want to add "to project 1" to all it's tasks.
