SQLite: Indexes are dropped if certain methods are called which internally call `changeColumnInternal`

Since `changeColumnInternal` drops the table and recreates it (which is necessary) but leaves out the indexes the table had before. The indexes are dropped with the table automatically **but not recreated**.

The affected methods are:
- ```RenameColumn```
- ```RemoveColumnDefaultValue```
- ```AddPrimaryKey```
- ```AddUniqueConstraint```
