    Fix a bug about add/del action dependency

    This patch uses session.refresh to get the lastest action record
    before each time updating action's dependency list to avoid
    possible desynchrony between different DB sessions. It also
    replaces the 'context' input parameter of _action_dependency_add
    method by 'query' parameter to unify the implementation of
    _action_dependency_del and _action_dependency_add methods.
