Make user and project profile links into Maniphest show only open tasks

Summary:
A couple of things here:

  - These links got fixed, but they show all user or project tasks. They should show only open ones.
  - Add an anchor so we jump you straight to the results, since the query UI is like a thousand miles tall now. We might take some other approaches here too, but let's see if this feels reasonable.

Test Plan: Clicked "View Tasks" from Profile and Projects. Executed some queries.
