[Bug]: Migration Manager not recognizing migrations from before current version

[nichwall]

What happened?

I am working on getting my first migration written (for the series duplication bug). Upgrading a database from 2.12.3 to 2.13.4 with a test migration occurring in 2.13.2 does not run the migration script. I assume this is because the migrationMeta table is being created with the current server version, so the migration manager sees the newly created table as having the same value as the current server version.

This may cause problems with future upgrades, or if people are upgrading from older server versions to a version after a migration occurred.

I am basing the migration script soley off of the README in the migrations folder, so I could be doing something wrong with the version numbers in my testing.

What did you expect to happen?

All migration scripts to run between previous and current version when creation of migrationsMeta table. When creating the table, the "old version" can be assumed to be 2.13.4 or similar.

Manually editing the versions in the table and then running the server again does correctly run the migration.

Steps to reproduce the issue

1. Use older database
2. Create migration script that targets a version between old database and current server version, without having upgraded to a server version that has the MigrationManager
3. Observe migration script does not run
