Fixed error with default values on older MySQL version

We have removed the default values for the columns completly, as it were only needed on SQLite when adding the column to existing row.
As this was done in an earlier migration, we can now safely remove it.

The MySQL now correctly detects no more changes. SQLite however still generates some wrong migration changes.
