Update repository method updateExpiryStatus to run only if Product table exists

This was done to fix the following error (taken from catalina.out):

Updating Product Expiry Status

Remove (name="user_role") from UserRole entity
Remove clearData() method from DonorRepository (See #137)

The need for the clearData() workaround was resolved by updating the
scheduled method updateExpiryStatus to only run if the Product table
exists.

Reverted back to using
`DatabaseOperation.DELETE_ALL.execute(connection, getDataSet());`.
