[PATCH 5/6] emacs/tree: call notmuch-hl-line-mode from tree-sentinel

[David Bremner <david@tethera.net>]

There is a a perceptible gap between when the tree shows up and when
the hl-line is visible, but this is better than the previous state
where the line did not show up at all until the user moved the cursor.
