bug: undefined in testimonials tweet links

[LukeberryPi]

PROBLEM

Some tweets in the DEVELOPER_TESTIMONIALS.LOG in the homepage are rendered without:

• a profile picture
• a username
• a user account name

Here are two examples:

tweet_007

tweet_010 (my own 🤩)

SOLUTION

Fix the testimonials Convex Query (or the data itself) to correctly fetch usernames.

Current behavior

The link assigned to the tweet_010 is https://x.com/undefined/status/1945204056063913989

Expected behavior

The link assigned to the tweet_010 https://x.com/lukeberrypi/status/1945204056063913989
