    Fix type of snapshot_id column to match db

     * Migrations create a snaphsot_id column that is an integer, but
       models incorrectly list it as a string.
     * The above issue causes errors in certain situations when trying
       to list instances. It seems to be only certain db configurations
       or versions of sqlalchemy that exhibit the issue.
     * Issue was fixed in trunk as part of a conversion to uuids in
       commit 407e16b863bac1dfbf4e954837009abf9c17f018 so a straight
       backport is not possible
     * Fixes bug 962615
