narrow: Fix incorrect values for use_first_unread_anchor. 

Apparently, we were incorrectly passing through something related to
opts.use_initial_narrow_pointer as the value for `use_first_anchor`.

If you read the logic in narrow.js carefully,
use_initial_narrow_pointer was unconditionally false.

The correct value for this attribute is when we're trying to narrow to
the first unread message in a given context.  There are two things to
check:

* then_select_id is -1; i.e. we don't have a specific message ID we're
  trying to narrow around.
* select_first_unread is True, i.e. we're trying to narrow to the
  first unread message.

A bit more work should allow us to get rid of the second condition,
but I'm not quite confident enough to do that yet.
