Subject: [PATCH] fix: guard constructTweet against undefined full_text

The longShortClass calculation reads t.full_text.length without a
guard, throwing a TypeError when a tweet object has no full_text
property (observed in v1.9.6.5 during renderTimeline on profile
pages). Fall back to length 0 when full_text is missing so the
class assignment matches the existing short-tweet behaviour.
