Make sure owner column doesn't get dropped during downgrade

Fixes bug 1204941

The owner column was missing from the table schema. Because of limitations
of sqlite and implementation details in SQLAlchemy-migrate, this would end
up dropping the owner column during a downgrade when using sqlite.

redundant conditions in paginate-query

For a list call on images, when a sort_key is applied, the query
generated has redundant values for 'created_at' condition. This happens
when the sort_key list has duplicate values.

Perform database migration snake walk test correctly

Fixes bug 1204940

The database migration snake walk test would not properly perform downgrades
leaving that part of the test non-functional.

Also, if downgrade was True, the test wouldn't downgrade all of the way to
the first migration because of a fence post error.
