agenda: Change clockinfo title truncation to preserve images.

The previous commit to remove truncation caused long titles that were not well
handled by some clocks.  This commit instead uses truncation based on string
wrapping, which maintains limited-length titles, but now preserves images
(e.g. emojis) embedded in the titles.
