    Call db refresh in Stack object refresh

    The current Stack object refresh doesn't actually do any refreshing,
    which explains the functional test speed regression since the RPC
    nested stack code relies on stack.refresh() to poll for state change.

    With this change AutoScalingSignalTest.test_signal_with_policy_update
    locally takes ~60s consistently. Without this change ~50% of test runs
    have some form of execution delay, taking 80s -> 300s+.
