PR: tiny-pilot/ansible-role-ustreamer#89

On this PR, the order of events was:

1. jdeanwallace gave me round 1 of notes (2023-01-05 9:37 AM ET)
2. I updated the PR and published responses to those notes (2023-01-05 3:46 PM ET)
3. jdeanwallace gave me round 2 of notes (2023-01-06 9:54 AM ET)

Expected

CodeApprove orders the options as:

1. "Since review by jdeanwallace 9:54 AM"
2. "Since my last review Jan 05, 3:46 PM"
3. "Since review by jdeanwallace Jan 05 9:37 AM"

Actual

CodeApprove orders the options out of chronological order:

1. "Since my last review Jan 05, 3:46 PM"
2. "Since review by jdeanwallace 9:54 AM"
3. "Since review by jdeanwallace Jan 05 9:37 AM"

@mtlynch ah thanks for filing this. This is currently intended behavior but I can see how it feels like a bug. Right now the first option is always "Since my last review" and then below that are all other reviews. I do this because I think that's the option most people are looking for and it could easily be buried under other reviewers in a multi-review situation.

I'll think about this some more and see if there's a way to make this more intuitive

"Since my last review" is a good first option if there have been changes since my last review.

The view I wanted to see was the diff of the last logical round (base: "review by jdeanwallace Jan 05 9:37 AM" vs head: "review by jdeanwallace 9:54 AM").

In this case, the first two options in CodeApprove's dropdown were empty diffs because I hadn't pushed any changes yet.
