[regression] Thank-you date is lost on editing contributions
A rather serious regression which IMO merits an out-of-band release.
To replicate
- Open a contribution for editing that has a thank-you date.
That's it. The page loads without the contribution date, and so it's lost on save.
This was introduced by https://github.com/civicrm/civicrm-core/commit/b4e8c2b4c3f3730a7193824dfb6452b86d5e31d7 which shipped with 5.16.0.
My quick fix is just to revert it, but others, particularly @pfigel, may want to chime in.
