N->O undercloud upgrade: Table 'nova_cell0.instances' doesn't exist

[Oliver Walsh]

https://review.openstack.org/#/q/I67c50fd5a5d2f4841ab26bce796a33efce0510b2 has caused a regression in the N->O undercloud upgrade where the nova db sync is running too early resulting in DB errors in nova api:
ProgrammingError: (pymysql.err.ProgrammingError) (1146, u"Table 'nova_cell0.instances' doesn't exist")

    Fix regression in undercloud upgrade cell_v2 setup

    For cell0 the order needs to be create_cell, map_cell0, dbsync.
    I67c50fd5a5d2f4841ab26bce796a33efce0510b2 reversed this, as a result the cell0
    tables are not created as it does not exist when the dbsync runs.
