Failing to migrate AdoNet grain reminders from Orleans 3.7.2 to Orleans 7

**Expected:** Reminders running in 3.7.2 on AdoNet Reminder Persistence should work in new cluster after running the scripts on the bottom here:
https://learn.microsoft.com/en-us/dotnet/orleans/migration-guide

**Actual** Reminders not running.

**Repro**:
https://github.com/runenilsenoe/orleans7migrationtest

**Steps to reproduce:**
1. `docker compose up`
2. run 3.7.2 app which starts a reminder
3. stop and run migration script
4. run 7 app and wait for it to trigger reminder.

Start with the linked orleans7migrationtest repository and follow its docker-compose setup. Run the listed migration scenario with the Orleans 3.7.2 and Orleans 7 apps, then inspect the migration scripts at the bottom of the Orleans migration guide and compare the AdoNet reminder data. Done means reminders created by 3.7.2 trigger after the Orleans 7 app starts.
