Summary:

Improve posting reviews to chat services, and fix a crash on empty reviews.

Review Request #12698 — Created Oct. 25, 2022 and submitted Nov. 1, 2022, 10:14 p.m.

Description

When a new review was posted without body_top text and no comment, we
fail to set the body variable, causing a crash.

While the crash is harmless, it does cause spurious issues in the logs.

This change fixes this, and improves the overall behavior in two ways:

1) If the body_top is "Ship It!", we now fall back to the first comment
(if available), rather than an empty string for the text.

2) If a comment is not available, it will now fall back to body_bottom,
which wasn't being considered before.

Testing Done

Unit tests pass. The new tests previously exhibited the behavior reported
by a customer.
