Delete `dag_version` table when downgrading the DB from the versioned Airflow

In dagcode, fileloc_hash column was a primary key on the version before dag
versioning. If dagcode is not deleted before downgrading, the fileloc_hash 
column,
created when downgrading, would be a null column that can't be used for a 
primary key.
A similar thing applies to serialized dag, which would have duplicates, and the
primary key can't be determined. The solution is to delete the dag_version 
table data,
which will delete the serdag and dagcode table data
